If you continue to provide high quality patches that lead to an improvement in FreeBSD's overall quality, you will one day be given commit rights. It's as easy as that.

Re: Wow! ixsystems.....
In response to Gary Kline kl...@thought.org:
Folks,
Late last night i finally surfed into the ixsystems pages.
WHile I haven't had a chance to check out the
price/performance ration and compare it to other sites [[or
maybe I'll do yet another roll-my-own]], I did happen on the
PCBSD link. It really does look like FreeBSD people who do
*not* wish to invest 101% of their lives getting
thing-to-work on the most stable OS ever. My one question
is: does at least everything that works under Ubuntu work
under PC BSD? I mean, things like setting my text fonts to
international? and being able to stream what streams {say,
FRONTLINE or NOVA} that PBS has.
Can i drop in a CD or DVD that I got from my pvblic library
and have it play without mucking around creating mount-points
like /media/dvd/0 and /media/cd/0? This is the latest thing
to break with my 7.3RC.2. The sound-juicer doesn't recognize
my music CD whereas my Ubuntu does. In other words, is
PCBSD closer to the Just-Works{TM} side of things?
There are forums and an active community for PCBSD. Those places are
going to provide you a lot more feedback on questions like this.
I don't _use_ PCBSD ... I have _tried_ it, and my experience has been
very good. On an IBM laptop, everything just worked out of the box,
and worked well. My problem is that I like to tweak, and I'm already
happy with my ability to tweak FreeBSD :)

The release branches (such as RELENG_8_0) get only very minor modifications from the time the release is made. The patches are only ones that address really serious issues, and the extent of the changes is usually very minimal.

Re: Re : building from source after freebsd-update
That handbook section is where I read: The default is to update the source code, the entire base system, and the kernel. First, freebsd-update tool sync the source. And in fact much of the /usr/src/ does contain source code. /usr/src/sys/ subdirectories seem populated, and some directories under /usr/src/usr.bin/ and /usr/src/usr.sbin/ contain source, while others only contain the Makefile. /usr/src/usr.sbin/sendmail/ contains only the Makefile. Which lead to the make depend error I experienced. It seems like I could build the kernel, and parts of the non-kernel base, but not other parts. After RTFMing, scroogling for days, and going through UPDATINGs and READMEs I'm still not clear on how to mix freebsd-update and building all or parts of the base source. I'm interested in being able to build system apps in the base, custom kernel modules, and eventually the entire kernel. Freebsd-update tool will update your base system and GENERIC kernel, using binary. If your are using a custom kernel, you must reboot on the GENERIC kernel (that have just been upgraded) and do your make buildkernel KERNCONF=yourkernel and make installkernel KERNCONF=mykernel freebsd-update is _extremely_ painless for tracking the security patches. It would be nice to be able to mix this with a certain amount of building source. From the Handbook : This utility provides two separate functions. First, it allows for binary security and errata updates to be applied to the FreeBSD base system without the build and install requirements. Second, the utility supports minor and major release upgrades. This tool is only available for RELEASE, not for STABLE or CURRENT.

Recovering base system files after failed installworld
Hi, I tried upgrading from 6.2 STABLE to 7.3 RELEASE, and everything went very smooth until I rebooted the new kernel. Make installworld failed complaining that cc1 was not executable. After a lot of tests, I came to the conclusion that the new 7.3 kernel had some sort of problem with my gvinum partitions, since executables were mysteriously becoming corrupt and the miraculously fixed after reboot. So I reverted to the old kernel and the system booted without any problems. I reverted with csup to 6.2 STABLE sources, but now I realize that some binaries of the base system were modified by the failed installworld. For example, it seems that libc.a is not compatible with the compiler as I now get: /usr/lib/libc.a: could not read symbols: Malformed archive Now, the question I have is: is there any way to revert all system binaries to 6.2 STABLE without a previous backup? Can a utility like freebsd-update help me restore these binaries?

Can a utility like freebsd-update help me restore these binaries? Yes. In essence what you need to do is obtain the 6.2 sources and run through a standard buildworld type update. In principle, you could use freebsd-update similarly, but 6.2 is out of support and not available that way. 6.4 is still under support, and the 6.2 - 6.4 upgrade should be a lot less risky than 6.2 - 7.3 if you're still eager t try freebsd-update. It is possible that you will have files installed by 7.3 still on your hard drive. Ones that don't exist in 6.X and so don't get overwritten by reinstalling 6.X. As the prime candidates for that sort of thing are the updated shlibs from 7.3, you need to check into that, and remove anything that shouldn't be there. Otherwise you can run into trouble if you update any ported software -- programs crashing because they try and dynamically link against two different versions of the same shlib. It's the same problem you can encounter after a major version upgrade (and the reason for the recommended practice of reinstalling all ported software), just in reverse. I don't recall any warnings of possible problems with gvinum compatibility between versions 6, 7 or 8. However, that does not in any way mean there weren't any, and you should check the release notes for the various releases since 6.2 carefully. It may be a worst case scenario of backing the system up, and then reinstalling from scratch -- in which case, a good strategy would be to have a RAID1 mirror (ie. gmirror(8)) for the OS and separate data partitions using whatever RAID level you had implemented using gvinum. Or else go the whole hog and build the system using ZFS. Either of those should give you good future proofing against this sort of thing happening to you again.

Re: Compose key and xterm vs. UTF-8
Christian Weisgerber na...@mips.inka.de wrote: Short: -- Why do compose key sequences fail to work in a UTF-8 xterm? And the short answer is: They work--if you know the right sequences. The compose key handling presumably comes out of some X11 library; xterm is just the recipient. The actual compose table used depends on the locale encoding. There is an index at $PREFIX/lib/X11/locale/compose.dir and you can find the tables in $PREFIX/lib/X11/locale/*/Compose. It turns out that the UTF-8 table is _quite_ extensive (6676 lines) and all the common characters I was looking for are in fact there. So why didn't I find them? Order matters. The ISO8859-* compose tables list two-character sequences in both orders. The UTF-8 table allows only one order. For the last twenty years I've been used to entering, say, aapostrophe to input an 'a' with an acute accent, but the UTF-8 compose table only accepts apostrophea. Oh well.
