FreeBSD 5.3 RC2 Released
ValiantSoul writes "FreeBSD 5.3 Release Candidate 2 was just released. This new RC includes an updated network stack that fixes a bug where the system stops responding when under severe network load, the complete disabling of the ULE scheduler due to instability, and other fixes. Originally the FreeBSD team decided not to release a RC 2 however the fixes in the latest CURRENT were important enough to do so. As long as there are no severe problems with RC 2, this will be the last test release until a final one. See the full announcement on the mailing lists."
Whell, FreeBaSeD is only on Version 5.3 - speak to the hand, thats so like 2002 retro - You aren't all that and a bag of potato chips.
Like whateva, Solaris is on version 8 and Fedora is on 9, Slickware is leading with 10, Gentoo is Gentoo is.... As if I would use something so not invouge. I run this click so I might just use 2003 since it has such highya numba.
Where is my lip gloss. Don't mess with me. I'm one crazy mo-fo. I once popped a cop cause he wasn't giving my props in Oak town. I've heard that somewhere.
If you're really concerned about the $.20 or the downloading, you should probably just track the branch using CVS until release. Is FreeBSD on 2 CD's now? I thought it was one disk, and one rescure disk.
I've actually given up downloading the entire thing and now just use the mini install cd. For me the first step after setting up a system is always updating the ports tree and installing from ports anyway.
This is just more proof that the folks over at FreeBSD are committed to releasing nothing that's not at-or-near perfect. For sure, nothing will hold the -RELEASE tag unless I'd run it at home if not in a production environment.
Personally, I'm happy that they're more concerned with stability than they are with the release schedual. The bugs in RC1 were pretty severe if not overreaching.
I am really impressed with the work that went into this RC. GDB fixes, plus work on memory allocations and networking data structures.
Bravo! I hereby increase my bid to $52,000.
Sincerely,
Jeff Merkey

"1. Why not fix the new schedular?" "2. Why did it take so long for them to realise it wasn't going to work" 5.x has been too slow. They want to release a stable, functional operative system. Despite of the lack of the ULE scheduler there're a lot of stable areas and new features in FreeBSD 5.X which people need in the real world to solve real problems. Hence the "need" of a 5.x-based "stable" release, to leave 4.x behind (just for mainteinance) and start to work 100% with 5.X. The ULE scheduler has some problems but it also has a lot of good things that work, it'll be just delayed to get maximum stability for 5.3. It looks like they don't want to have Yet Another Delay. Other operative systems (linux 2.6, windows, other BSDs) are also a natural competition for freebsd and freebsd needs a stable 5.x to face them because 4.X is just old and misses lots of features. I'd guess the ULE scheduler will be fixed and enabled by default in 5.4.
[Man with OS slung over his shoulder] 'ere's one!
[FreeBSD, slung over shoulder] But I'm not dead yet!
[Man with cart] 'e sez e's not dead.
[Man with OS] Don't mind 'im, what does he know?
[Man with cart] Well
[FreeBSD] Netcraft? Netcraft! Well, that bloody does it!
FreeBSD jumps off the second man's shoulder and begins to club both men, vigorously.
See what I've been reading.
...includes an updated network stack ...
In other news, Microsoft has declared they have just improved the network-stack of Windows XP, making it more robust under heavy loads....

What is the best way to upgrade to this version? Download the CDs? Through the ports? Do you have some sort of strange method that no one else has heard of? The answer falls under then 3rd option. Although every FreeBSD user should have heard of it. It's called cvsup. Take a look at the FreeBSD handbook. It will describe the process much better than I ever could. Look for the heading "make world".
Understanding is a three-edged sword. -- Kosh Naranek
The ULE scheduler was supposed to be the default scheduler. It was placed as the default in 5.2. Between 5.2 and 5.3 kernel preemption was enabled. Some serious flaws in ULE popped up leading to crashes and other instability. Due to the complexity of ULE and preemption together only a handful of core people are able to fix this.
Since 5.x has been hold back long enough it was decided to drop ULE as the default scheduler for 5.3 and concentrate on releasing 5.3.
This doesn't mean that nobody is working on fixing the problem nor that ULE will not be the default scheduler. It is just going to take a while before it happens.
The reason for totally disabling ULE in 5.3 was to focus on other bugs in 5.3 and fix ULE on current (6.0) and then backport this to a later 5.x release.
I suggest you read cvs-src summaries at http://www.xl0.org/FreeBSD/ which gives a view on what is happening on current.
You should settle to this method as it is the preferred way of keeping your system up-to-date, wether on updating between releases or incooperating security or maintainance updates from the respective RELEASE branches.
Basically after having your source updated to the latest RELENG_5_3 branch, typically via cvsup(1), it consists of the following steps:
# make buildworld
# make buildkernel
# make installkernel
# reboot
single mode:
# mergemaster -p
# make installworld
# mergemaster
# reboot
It is very straight-forward, still be sure to read about the details in the handbook.
Let's not get too huffy here about ULE. Anyone care to bring remember the ugly VM wars of the early 2.4 series? Even now there's still plenty of LKM traffic over scheduling in the 2.6 kernel. The unfortunate thing is that I think a bunch of the work is for naught. I believe Dragonfly (at least in concept) will end up being much more scalable. If that proves true, I'd hope that down the road they re-merge to focus resources on IMHO is the most robust of the FOSS OS's.
> i'm using 1024x768 @75Hz (128 columns of text!) and it's a dream for coding in. i don't wanna use X, so only way i'll be happy in fbsd is if i can get big BIG console windows like this. anywhere from 128 to 132 cols is good enough for me.
(i already checked fbsd web site man pages for wscons, and it looks like 800x600 with 90 cols is the max???)
First of all, you'd need man syscons, not wscons.
At any rate, I'm currently using 132x43 character mode on my console, which works fine as logn as you have a graphics card with a vesa 1.2 bios or better, and have enabled vesa support (either by compiling it into your kernel or by loading the vesa kernel module)
800x600 (with 90 text collums) seems to be the maximum for graphics mode with syscons, but for character mode it seems to rather support anythign that your vesa bios supports.
Som if all you need is a 132x43 text mode screen, then yeah, that will work fine. If you need graphics mode, checkout the manpages on vga, vgl and vesa and see if that woulf work for you.

I did Tux last year with a stencil I found on the net so this year I made the daemon one from scratch. Kinda rough in a few places but overall, I was pretty satisfied with the results.
Cheers,
I really need to disagree with the previous two posters on this. The early adopter's guide recommends backup-install-restore rather than cvsup from source.
Anyone who can read the handbook should be able to install it and use it. The problem is that not many people (including myself a year ago) want to spend the time to RTFM. The handbook really is well put together though. FreeBSD certainly isn't as "easy" to get up and running as Fedora or Mandrake, but it's certainly possible. Only severe issue I've had with FreeBSD lately is with my Compaq laptop. If you want to run FreeBSD, avoid Compaq like the plaque. I can't even boot into the installer (it shuts the machine down). At least it runs arch linux...
