UPDATE Re: Upgrade from 4.0 to 4.0.1

[Daniel Gimpelevich]

It shouldn't make any difference to you whether you're at 4.0 or 4.0.1
prior to a "yum update" because after you do that, the system will be
current, with packages even newer than a fresh 4.0.1 install. Just do
that, and don't worry about whether your system is fully or partially
upgraded from 4.0 to 4.0.1 first, because that will upgrade it even past
the 4.0.1 level. The only thing to watch out for is that if yum installs a
newer kernel, sometimes it will redo the bootloader setup with it, and
sometimes it won't. I haven't yet found a way to predict when this
happens. So, after you "yum update" everything, edit /etc/yaboot.conf
(assuming NewWorld) so that it is pointing to the latest installed kernel
and its associated initrd. At this time, that's the 2.6.10-1.ydl.1
version. It may be that no changes are necessary to the file. After
examining and/or editing the file, "/sbin/ybin -v" for good measure. That
makes the settings in the file take effect on the next boot.

If your "yum update" is not succeeding, yum tells you so. This is one of
the reasons why making a "yum update" cron job is a very bad idea. One way
to prevent yum from failing is to replace the download locations specified
in /etc/yum.conf with a reliable mirror that isn't too far away. For
anyone in North America, I highly recommend sticking with the USherbrooke
mirror in Quebec. The default of ftp.yellowdoglinux.com is best not to
use.

Also, there were problems with the kernel packages for G5s. As a result,
ASSUMING YOU DON'T HAVE A G5, you must remove those packages before you do
any kind of yum update. You remove them by typing "rpm -ev kernel-g5" and
"rpm -ev kernel-g5-smp" so that yum won't try to update them.
