It is possible that Kay Sievers is now also the maintainer for (the userspace portion of) udev, but as far as I know, udev is still the brainchild of Greg Kroah-Hartman, and Sievers and that Lennert guy - Lennert is his firstname actually - are the ones behind systemd. >> Many of the newer releases of other distributions have already >> switched to systemd by now, e.g. Mandriva, Mageia, openSUSE, possibly >> PCLinuxOS, et al. openSUSE 12.1 is the only still very new distro >> release that actually still supports - and documents via their >> website - removing systemd and installing the "old" (but improved) >> System V init scripts. > > well, long live Slackware then, good news :-) Yes, I don't expect Slack to be switching to systemd any time soon. However, since the new udevd release now installs itself under "/usr", the breakage is already introduced, and so sooner or later even Slackware will have to adopt the new udev, and will no longer be able to boot without an initramfs or initrd if you happen to have "/usr" on a separate partition. Well... That is to say... There is a workaround, but this will still require that "/usr" be mounted even when booting up in single-user mode. The workaround is to, instead of using an initrd/initrams - for instance if you roll your own kernels - use a pre-init script which mounts "/usr" (and whatever else you would like it to mount) and then calls the actual init via exec, like so... (Note: location of GNU Bash and init adapted to the future scenario and using ext4.) #!/usr/bin/bash mount -t -ro ext4 /dev/sda2 /usr exec /usr/bin/init You then store this script in, say, "/sbin", and then you invoke it via the kernel's parameter line in the bootloader - for LILO, that's on the "append=" line - like so... append="init=/sbin/pre-init.sh" But of course, that too will break if "/sbin" is going to be a symbolic link to "/usr/sbin". So they are really pushing the initramfs route. (I hate those things. :p) >>> So, I'd think it's not only that -F on shutdown was removed from RH >>> but that RH is now removed from distros list and should shutdown ;-) >>> >>> (hey, we're in colmisc after all ;>) >> >> This isn't RedHat's first sin, and it won't be their last either. >> They see themselves as an important component of the upstream >> GNU/Linux development and as wayshowers/enforcers. > > so why is it that they sound so much like showstoppers and puncturers? Because they are pushing their agenda. RedHat is in rather close cooperation with Oracle, which has acquired Sun Microsystems and has thus since become the "intellectual property" owner of Solaris. And Solaris does it that way too. >> ... >> ext4 is cool - I've given it a test run and I can't say that there's >> anything wrong with it insofar as I could see - but I still prefer >> XFS, > > yup, I usually prefer JFS and XFS to ext4, though I like some > easygoers in ext4 like resizing both ways or self supported undeletes. Like I meant to imply, I haven't played around with that yet. I've only given it a quick test run so as to check its performance - not by way of benchmarks but simply while using it - and it seemed like a very usable and fast filesystem to me. But either way, I expect that ext4 too is soon going to be deprecated in favor of btrfs, which some distributions are already beginning to offer and push. btrfs is quite advanced and offers many of the possibilities of Solaris's ZFS, but it's still "not quite there yet".

However, our organization is also already defunct for a few years, so my experience with CentOS is a bit rusty too. I think that the last version I installed - on a server which I own myself but which has in the meantime been reformatted and is currently non-operational - was CentOS 5.3. As for Fedora, never liked it and never will be using it. Completely unreliable, and you still get RedHat's not-so-benevolent dictatorship on top. ;-) -- = Aragorn = (registered GNU/Linux user #223157)
