Will Image Installs Benefit Vista Adopters?
Reader MarkByers calls the article "stupid":
The final linked article starts with this dubious sounding statement:To this, mwalleisa points out that "When talking about using Symantec Ghost (or other), the author is referring to Windows XP installations, not Vista.""The bottom is about to fall out of the market for imaging tools like Symantec Ghost ... The Vista install DVD is, in fact, just one big system image."
But then immediately contradicts itself by pointing out:
"But this flexibility only extends to the installation of Windows itself. To clone a full system with apps installed, Symantec Ghost or a similar utility must be used to create that image."
People don't use Ghost to make a copy of an unconfigured fresh install of Windows, they configure it first, then Ghost it. This new installer will have no effect whatsoever on sales of Ghost, or any other imaging software. After such a terrible start to the article, I'm not sure it's even worth reading the rest.
neonprimetime had a different objection:
This wasn't a Pros & Cons. It was a love-fest [for] the new image-based install process. Everything he wrote in that article was happy go lucky, no cons in sight.
- "This means that the image isn't a bit-for-bit image of your disk layout, and hence you can apply the image to a new system without destroying the contents of the hard drive."
- "Vista is hardware-agnostic, so you can use a single system image as a source for multiple hardware platforms, even if they have quite different hardware configurations.
- "When capturing a system to a WIM file you can specify exclusions. For example, you can have a work directory on the system with temporary data.
- "Interestingly you can have as many images contained within one WIM file as you think you can manage, and any one of them can be marked as bootable."
brunes69 mocks the article's introduction ("However, all this is about to change. Windows Vista is based entirely around Microsoft's Windows Imaging Format (or WIM), a file-based imaging standard rather than a sector-based. this means that the image isn't a bit-for-bit image of your disk layout, and hence you can apply the image to a new system without destroying the contents of the hard drive."), writing
Along similar lines, namityadav wondersWow how revolutionary.
Oh, hang on a second while I untar this archive ....
So is this revolutionary install concept an exact copy of what we see in Ubuntu?When it comes to installing an OS, not everyone wants a one-size-fits-all install which can later be trimmed; "[C]opying a bunch of files is the right way," contends reader radarsat1, who doesn't look forward to the change in Windows' installer:
Damn it, one of the things that always annoys me about Windows is that it's not as simple as copying a bunch of files. This is mostly due to their inane and outdated drive lettering scheme.Reader yagu has a related complaint about the difficulty of installing Windows as an equal player along with other OSes:In Linux (or any Unix), I can move my installed system to a different drive or partition just by copying it. I can install an entire system within a folder of another system. All I have to do is change my drive mounts, add some symlinks, or use chroot, and I can put the entire system anywhere and it's as if nothing changed.
When my Dad bought a new hard drive because his old one was dying, we tried in vain to copy his old system over to the new drive. First we tried imaging it using "dd" on a liveCD, but that didn't work. Then we tried making a new filesystem and using "cp" to just copy the whole thing. That didn't either. We didn't want to spend money on Norton Ghost, just for a one-time thing.. He ended up having to re-install and re-activate XP, re-install all his MS Office software he'd had some trouble with installing in the first place, and finally setting up a whole new system. Just because he wanted to replace his drive!
That, compared to the number of times I've moved my Linux system without a single hitch... I can't believe people put up with this crap. Now instead of keeping things simple, they're moving even further away from a file-based approach?
This reminds me of other Microsoft installs I've done over the years, and it smacks of such disdain for the rest of the OS universe. Nowhere in the article, nor can I find evidence anywhere else is there an accomodation for an install where XP is just another OS. I remember my first experience with this, when I installed a Win98 on a Linux box, and not only did Win98 not offer a dual boot, it (seemingly) gladly removed my Linux MBR and formatted my partition without asking if it was okay, and without saying it had done so. That was quite a surprise.Reader dreamchaser sticks up for Microsoft's decision not to make multi-OS systems easy to create:Does anyone know if there is a way to do this? (Though, knowing XP can point to more than one OS to boot, I'm guessing Microsoft is more gentle if there is a pre-existing Windows OS there.)
I've googled for dual-boot information, it looks to be similar to what I already know.
Just to play Devil's Advocate here, but why SHOULD they facilitate the use of other OSes? Look at the customers who make up 99% of their base:kailoran points out one big difference, which is a pretty persuasive one to anyone who doesn't care to have Microsoft dictate the layout of their hard disk:
- Home users who buy a machine with Windows pre installed. No worries about dual boot here.
- Corporate users who load a custom Windows image on new machines. No worries about dual-boot here either.
Also, if it really is just an image it would be a simple matter to just load it onto a partition then set up dual boot using GRUB. Anyone who feels they need dual-boot probably already knows how to do it. Most modern Linux distros do a pretty good job of it for newbs too.
Very very very few people NEED dual boot. Some do. Most do not. From Microsoft's point of view, why should they facilitate it when the people who really need it (i.e. developers) will have no problem either setting up dual boot or using virtualization?
The thing is that unlike the Windows' MBR, grub can actually be configured to run the other OS if the user wants. Most distros auto-detect and add the appropriate configs, so that there's zero effort needed.An image-based install from Microsoft isn't completely new; Aslan72 says he "hated it when it was called RIS," writingInstalling Windows just nukes the existing MBR and the only thing you can do is run Windows, or start searching for a rescue CD/floppy.
I'm partly responsible for an image that goes on around 5-600 machines at a Midwestern University College lab. We tried RIS when it was out, but although it was cool, it was simply not practical. The savings of having 'one' image really didn't outweigh the impracticality of it taking 2-3 hours per workstation per lab.This is no different; currently it doesn't support multicasting and so although it's 'revolutionary' (read: RIS) it still doesn't beat the ability to push down and image to a workstation is less than 20 minutes...oops, did I say a workstation, I meant a lab.
It still won't beat Ghost any time soon, IMO.
To that complaint about multicasting, reader gruhnj writes
Windows Deployment Services, the replacement for RIS that will be coming out around the same time Vista ships, does exactly that. RIS only does the OS install well. Once you create your master image, you can place that onto a WDS server and multicast it out to as many computers as you have bandwidth. My current image when run deployed with imageX comes in at 25% less space (both images on max compression) and deploys in aprox 12 min for the image copy, plus the normal mini-setup time.Ghost aint going away, but it will be eaten away from at the bottom with WDS.
Elsewhere, readers discussed the image formats and metadata in greater depth: To EXMSFT's query "I don't believe TAR includes ACL and metadata information related to the filesystem. Or does it?", reader pavon says "They can be," and provides some details:
The tar file format, like most unix things has undergone several revisions and branches. In POSIX.1, a new format, called the Pax Interchange Format, was created as a backwards compatible extension of the tar format, that allowed for storing of arbitrary metadata. How this metadata is used is naturally left up to the system's implementation of tar and pax. I don't know how widely these extensions are used. I know that in Mac OS 10.4, metadata including resource forks are supported, but I think they implemented them using thier normal flat-file hacks (._myfile holds metadata for myfile), and not the pax extensions. This man file has a little more information.
There are complexities beyond simple metadata capabilities, though. An anonymous reader points out that
There's even more to think about besides ACLs. There are a lot of components in Windows and not all of them come with every version (Home, Media Center, Server, etc.) plus computer vendors want to customize by adding software or changing the default configurations of apps. Many of these components need to be installable as runtime as well as during install, and some components may be incompatible or require complex logic to integrate (for example, installing a component might require adding a new user or group to the system).
What you see during a Vista install is only a small part of the new world of the Vista installer.
Many thanks to all the readers who took part in the discussion, especially those quoted above.
maybe tomorrow we can have an article about the article about the article about image installs in windows vista.
Think of all the time users can save by including thier ever-so-helpfull smiley clickies, special cursors, and Bonzai-Buddy right into the install disk.
It will benefit some greatly, Some will will be neutral, Others will not benefit and it will harm them.
But I think it is going to benefit more then it is not going to benefit, just with faster Install Time.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
Chances are the install is going to work. I think people should focus their attention on the OS after it is installed. That's a lot more important if you ask me. I can guarantee that it will be friendly towards OEMs because thats their bread and butter. It's a non-issue.
http://religiousfreaks.com/Raymond Chen has discussed the logic behind Microsoft's approach to multiple OS installs, and frankly, the logic isn't that far off.

90% will use a pre-installed OEM version anyway, so don't bother.
But it's still going to take quite a bit to rip kick/jumpstart from my networks. Throw either of those on a DVD and you still can maintain flexability to install on multiple hardware configs, including your favorite database or webserver.
There are no loopholes. It's either legal or it's not.
I don't have time for that. I'd like the Cliff Notes for the Cliff Notes for the article on the article.
/. is pushing the boundaries of the revolutionary usage of the enormous resources of the Internet. Next week on this very site, we will have an article, which will refer to the current article, but instead of simply copying +5 Interesting/Insightfull posts, /. will post IMAGES of these posts in PNG format.
You can't handle the truth.
how will the new installer differ from using Norton Ghost?
Step 1: click "Preferences" link
Step 2: click "Homepage" tab
Step 3: Unselect Backslash category.
Step 4: We all profit from not having to hear you whine.
DONE.

Can we make the Backslashes smaller like the lesser stories? Some Backslashes, like this one, just aren't useful to me, but I can't filter out specific Backslashes very easily.

The real advantage to the improved imaging from microsoft is they have done away with the Hardware Abstraction Layer. That means I can create one image for many different systems. In theory I could use the same image on a HP desktop as on a Sony laptop. This is a very nice enhancement.
What could possibly go wrong?
some kind of new meta-dupe?
sic transit gloria mundi
Yes, I did send a letter and call tech support with the suggestion - but had no illusions that a large corporation would actually listen. I did expect them to come up with something so obvious on their own. I can't believe that 4 OS generations later, drive letters are *still* causing problems. There is some kind of symlink used by the GUI, but they seem to be executable (!?!) and used as a virus vector.
I switched to Linux while waiting, and have been appalled at the increasingly evil behaviour of Microsoft corporation (although I know some nice guys who work for them). Now I am just thankful that they didn't patent symlinks.
Seriously though, it's like that annoying stuff networks do on series shows, IE Lost. The first 10 minutes of the show is about what happened last week, then the last 10 minutes are whats going to happen next week. An hour long show only has about 25-30 minutes of content you haven't seen twice or haven't been prepped for already. And, as if seeing it in triplicate isn't enough, at least once per season, they will not only devote the first and last parts, but the ENTIRE show to a recap. This story reeks of (looming deep voice:)"Last week, on...SLASHDOT..."
Windows has more viruses because linux has more virus coders.
I read the article. And perhaps the article wasn't targetted at "Joe User", but at the more technical crowd.
I STILL don't see Vista shipping with a tool that makes it easy for a given user to do something as simple as swap a harddrive. That is what millions of users want, and still don't have. Even ghosting or copying bit for bit doesn't really help. I want to back the thing up easily and quickly (single button click) onto a DVD or CDR and be able to reinstall the whole darn thing.
I suppose someone out there is going to point me at some software that claims to do it, but I use computers quite a bit and haven't seen the one click equivalent. I shudder every time my father in-law comes to the house and says "my hard drive is full..."
This snippet: People don't use Ghost to make a copy of an unconfigured fresh install of Windows, they configure it first, then Ghost it. caught my eye.
I do just THAT.
I have an XP Pro image Sysprepped to include most of the chipset, display, and NIC drivers I run into. Another for a client has a hosts file populated with their servers to simplify things. Works great. I skip most of the BS in copying files, and go right to HW config. When I need an disk driver, I have a ramdisk loaded with several that I select in a DOS menu. It's now on DVD, won't fit on an overburnt CD any more. Driver bloat. I hate them all.
Ever try installing Server 2003 on hardware that needs a disk driver without a floppy? Like an HP 580 with SAS drives? Ick.
I think image-based installs are wonderful, where they actually work, and even if Vista is no more than Sysprepped install, it's great.
Maybe Microsoft will sport over the MD5 checksum so we can make a Starbucks run while it computes.

deleting the extra space after periods so i can stay relevant, yeah.
You mean I finally have to fucking register?!
I usually find Raymond Chen to be very entertaining, and the man's prolly several orders of magnitude smarter than me, but frankly, he's full of crap.
It's perfectly reasonable to cram a "don't fuck the mbr kthnx" option somewhere buried a few menus deep, alongside any other three letter acronym option that shitty little setup has as it is.
If I have a "foreign" boot sector, and I done gone told you specifically "don't fuck with it", it's now my problem whether or not the other boot sector can find windows.
Shit son, it's not like the thing doesn't require it's own partition nine out of ten times.
--
Someone in charge of coding these things prolly forgot to check whether the mbr already had anything in it before blowing it away and someone higher up figured it either too inconsequential or advantageous (insert favourite anti-trust conspiracy theory here) to bother with.
Not really those of us who are too lazy but more those of us that just don't have the time. Saying that as a person who's only just realised how handy Backslash can be. This post was really helpful in giving me a quick overview on some thing I'll have to look into in a few weeks and since I'd missed the original story when it came out it was handy.
I ate your fish.
So file based installing screwed his dad, yet now file based copying is something this person thinks Microsoft should keep?
Oh, and as an aside to the person who wrote that....The program you were looking for was DriveCopy. It's designed to move partitions or entire drives, resizing as necessary. I've upgraded HDs in my desktop for years without ever having to reinstall the OS or the apps.
Have a look here... http://backslash.slashdot.org/faq/UI.shtml#ui500 Then go to your prefs and the homepage settings and you should be set. Cheers, ZzzzSleep.

Ghost will not go away. Sure, maybe ADS can multicast. But ADS is an addition to Windows 2003 Server ENTERPRISE. Ghost Server runs on any old desktop.
I have 25 remote offices with 20-400 machines each. None of those remote offices have an enterprise edition server, and there's no way I'm going to buy Server 2003 Enterprise for all the offices just so they can image machines (and I'm certainly not going to have them pull images across the WAN). Instead, they all have a P4 desktop running XP that can multicast to a hundred machines in 20 minutes.
Ghost is not going anywhere.

The biggest advantage of this will be for those creating cracked versions of Vista. I predict that someone will figure out how to create a Vista install DVD ISO with any desired installed programs, changed settings, etc., by using this new Image Install. Then the race will be on to create the ULTIMATE Vista ISO. It will remove all the extra junk, kill the copy protection, tweak the settings, and come with Firefox, Photoshop, the latest video codecs, DVD ripping/copying software, etc. all installed and ready to go. This will result in a much nicer version of Vista than what you can pay Microsoft to give you.
I think not!
Most everything in Windows 2000 and up is now reckoned relative to abstract locations.
At boot time, the boot.ini doesn't have a notion of "C: drive". It's an hardware-relative path to the partition and specific kernel image you want to boot.
Once booted, the "C:" drive is just what's substituted for %SYSTEMDRIVE%, which is the partition you booted from.
It's a fixed alias, really.
Consider it the same thing as the unix root '/'.
All other volumes can either be mounted at "new roots" (other drive letters) or to paths in the root file system (like in Unix).
Unlike in 95/98, in 2000+ just changing the order of drives in the system doesn't change the letters. Windows stores volume IDs and serial numbers in the registry along with the last mount point or volume label. You set it and it stays like that.
You don't have to worry too much about (properly written) programs fucking up because you relocate a volume. Registry settings are supposed to be made from relative constants derived at boottime. By relocating the pointer in the registry that defines the property, you can then move the volume, and reboot without much issue.
%SYSTEMROOT%, %PROGRAMFILES% for the system,
%APPDATA% and %USERPROFILE% for logged in users.
And in the registry:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList]
ProfileDirectory=%SYSTEMDRIVE%\Documents and Setings
Most of Windows itself in XP that I've noticed is clean in this regard. I've moved around Program Files and Documents and Settings folders without issue.
Also, there's soft links in NTFS. They're called reparse points. Unfortunately you need to get the 2000/2003 Resource kits to get the tool to manage/use them. They're transparent to OS software, which is good. Unfortunately (or maybe not) there's no evidence of it or exposure through the windows shell.
THIS THING CAN TURN ON A DIME, MACROSSZERO STYLE ALSO FUCK BETA, ~NYORON
well, nt will let you boot any partition you want.
did you ever wondered about the instal in the mbr / instal into the first cilinder of the partition offered by lilo/grub?
that's for having it booted via the chainloader of nt....
I expect a little bit of knoweledge from a poster about what it's posting
Firstly, you can install vista on any partition. It does not have to go to c: drive. For this to work, (and its dodgy new bootloader), it has to diddle the c:\ drive in any case. It creates a directory "boot", and moves ntldr and ntdetect.com there, and puts its own boot manager in there.
Secondly, it is not preconfigured for any given hardware or partition. So the WIM simply delivers a windows ready to be configured: the OOBE (out of the box exploit) does this. OEMs have been delivering what is called "unsealed" installs for a while in this manner.
What makes WIM a nuisance is that it can only run from a vista boot (ie you can't do the setup from Windows NT4 (like i have done several XP installs). The image files can be modified, but only from a running installed Vista. That is, even the WinPE that installs it can not make the WIM files.
On the other hand, if you get everything to work, you can get a nice little fast-booting Windows repair disk. The setup WIM is actually a full-blown WinPE which has been hobbled to run setup. Kind of like making Windows XP and hobbling it by putting "shell=edlin.exe".
BTW, OS/2 has been used to run specific applications via "shell=", as has Windows 2.x and 3.x. Windows Runtime was nothing more than Windows with "sol.exe" as shell.
I gave vista something like 16 gb in some drive like J: on partition 1.
OS/2 - because choice is a terrible thing to waste.
Get squashfs 3.0 and mksquashfs your source filesystem.
unsquashfs it to the destination.
You can build, add, delete files from the filesystem using the same tools, and even just mount it as a filesystem.
We use it at Genesi for our Linux installer. However.. squashfs 3.0 is pretty new, we had some serious problems getting it to unpack and restore setuid bits. Windows should be a hell of a lot easier as all the permission information is in ACL's and can just be shoved in as an NTFS stream, we can't do that for ext3 and squashfs
I would love to see LZO and bzip2 (or some other nice format..) in squashfs, to improve performance or provide crappy performance but insane compression benefits.
The thing is that unlike the Windows' MBR, grub can actually be configured to run the other OS if the user wants.
Windows' bootloader can boot anything you damn well please. Stick the boot sector in your root drive and add an entry to boot.ini for it. Works pretty much the same way grub does when loading non-multiboot-compliant systems.
