rwd0d is the raw device (r) of the first IDE disk (wd0), using a special partition (d) that spans the disk from the very first to the very last byte. I *think* it's the same as hda under Linux, but I'm not sure there.

Ghost for Unix

Of course there is nothing new in g4u, it's just Unix after all.
But why spend an afternoon surfing the web for alternatives to Ghost, DriveImage and friends when you can rewrite your own version from which you know what it does, and while there get famous on/.?
- Hubert
P.S.: Does Ghost etc. support Gigabit Ethernet? USB Ethernet? Token Ring? No? Of course not - have fun finding the necessary DOS drivers. See the g4u webpage for reasons why I wrote this.:)
Help how? If you follow the instructions on the web page closely, you will see it'll warn you to ignore the errors (well, the first ones - missing 'rm' is a hitch I'll fix in 1.9:-).
After that, you should be able to deploy the disk image.

1. slow: yes. It reads the whole disk and compresses it, then when it's moved over the net it's decompressed again and written back to disk. Esp. compression is very slow, at deployment the bottle neck is somewhere between disk and network.
The only way to work around that is to add some intelligence WRT file systems, which is exactly what tools like ghost etc. do. g4u does not do so to remain simple, and be able to clone _any_ operating system or combination of operating systems. See the web page for more background!
2. bit corruption: do you trust your harddisk to give you back the bits you hand it over? I do, and if we can't do that one day, we all have a problem.
Um, it's _usual_ for _any_ Linuxday (that I've seen) that there are a few geeks, and only clueless people otherwise. That's what we all like about Linux isn't it - new land to discover?:)

Sun Professional Services uses SSH to access the machines they are administrating. I guess if it's secure for all their customers, it should be good enough for the application in question too.
VM is handled the usual way using MMU, pages etc. If it comes to swapping/paging, you can configure a local partition to do just that. If there's no backing store, the allocating process has a problem.:)
Some 20 years ago, another open source operating system development group[*] had the same problem. At that point, several people had access to the source tree, each one supervising a certain area, reviewing and accepting patches for his area.
When that wasn't enough any more, several people were brought aboard to handle one area.
That's how things still work today, with a core team doing architectural guidance, developers who have write access to the source tree and who can make modifications on their own, of sent in by contributors and reviewed by the developers.

All we really need is a decent text processor, and that's what FrameMaker would be. Unfortunately, the marketing crew of Adobe decided to can the Linux version (which still works fine here on NetBSD, when I reset the system date;-).
Of course even if there was a FrameMaker for Linux the price is another thing...

Personally, I need binaries for:
* Solaris 8/x86 (!)
* Solaris 8/sparc
* NetBSD/i386
I canot really comment on the fact if the developers' team is understaffed or not, but I'd prefer if the people would concentrate on the web browser. I know where to get a HTML Editor/Mail/IRC/whatever when I want one.
But that's probably just me. If software doesn't include the kitchen sink today it's not complete.

I'd like to see this (at least) for NetBSD too, and maybe not only for PCs.

I did a 45-machine cluster with g4u, see
www.feyrer.de/marathon-cluster/
(Of course the machines were running NetBSD too, doing a video rendering job)
- Hubert
I guess I should really add this next time.
:-)
For now you can do:
dd if=/dev/rwd0d of=/dev/rwd1d bs=1m progress=1
(Yeah, that's Unix! I will give you a shell wrapper in g4u 1.9. Suggestions for a name, anyone?

That's interesting... we use g4u to deploy images with Solaris/x86 and Win2k, no problem there.
Did you use different disk sizes in the process?

Um, maybe not all PPC hardware is made by Apple?
Look at the list of NetBSD ports that use a PPC:

Of these, only 1 runs OSX.
All of them run NetBSD though.

* Drum'n'Noise: very beat-oriented, but lots of distortion.
