Shuckydarns, hendrik. I'm gettin' spooked about this whole thing now.
Thanks for the info. I have not been able to find a tutorial to upgrad
the newer kernels/distros since a 2006 post. Appreciate the reply.

Yeah udev needs 2.6.27 or higher, so you have to upgrade the kernel first,
then reboot, then do the whole upgrade.
I have no idea what the plan for handling the upgrade is officially.
Maybe the release notes are supposed to offer some hint.
I've had problems like this several times, in several upgrades from an
old stable to a new. Sometimes X, sometimes udev, and once running out
of disk space for the upgrade. Usually I end up with an unusable
system. Not acceptable for a production system.
As a result I always copy the old stable system into separate
partition(s), so that when an upgrade fails I can boot into the other
copy and have
Because of these problems on a production machine, I've gradually
learned to copy the old stable system into a separate partition, and
then chroot to that to upgrade the copy while the old system is still
Of course, things go wrong this way, too. Some packages want to
fiddle with /proc during upgrade, and it isn't there. I'm not at
all sure whether to provide it. Often things can be patched by booting
to the incompletely updated new system and resuming the upgrade. This
does reduce the amount of time the productin system is in an unusable
I'd really like it if there were to be viable instructions in the
release notes how to upgrade in a chroot, but I've never seen them.
