It seems this was an ordering issue. Ordering was changed a lot in 1.3
and newer (it interacts with dpkg much closer), so I assume that's fixed
now.

Title:
udev initramfs hook ignores that udevadm is disabled, copies it anyway
Status in apt package in Ubuntu:
Fix Released
Status in apt source package in Karmic:
Won't Fix
Bug description:
Binary package hint: udev
I've just experienced a perfect storm of bugs during an upgrade, which
I will relate here for its amusement value rather than for its
relevance in fixing the bug that I am currently filing.
During an upgrade to the latest karmic - which somehow managed to find
over 150 distinct packages in need of upgrading - the 'restart udev'
command in the middle of the udev upgrade hung.
'sudo initctl log-priority debug' also hung - in the 'sudo' part, not
the 'initctl' part. Trying to run 'sudo' anywhere else obviously also
hangs.
Switching to VT 1 and trying to log in, the login is accepted... and
then hangs right after pam_motd, without giving me a shell (this
points to pam_ck_connector having problems).
So switching back and forth between X and VT1 and trying a few
different things to get myself unwedged, something gets confused on
the audio side, causing my speakers to repeat a single sample from the
music I had playing. So I try to kill pulseaudio and get it to
restart.
Killing pulseaudio alerts gnome-settings-daemon, which tries to
reconnect, which hangs... thereby hanging metacity.
So now I can't type in any of my X terminals either.
So I use SysRq-E, which succeeds in killing the processes and
respawning them... aside from the fact that X comes back without a
keyboard or mouse.
And of course openssh isn't managed by upstart yet, so I can't log in
remotely.
So I reboot, and that's when the fun starts... because among the
packages that was upgraded before udev hung was the kernel. Which
means that when the package was configured, a new initramfs was
generated... while udev was in an unconfigured state. Which means
that when /sbin/udevadm was copied into the new initramfs, it wasn't
/sbin/udevadm.
Output I should never see from my initramfs at boot time:
udevadm trigger is not permitted while udev is unconfigured.
udevadm settle is not permitted while udev is unconfigured.
Fortunately, I had an earlier kernel installed so I could boot from it
and recover - but the udev initramfs hook should *never* do this.
Either it should explicitly grab /sbin/udevadm.upgrade if present and
copy it in place of /sbin/udevadm, or it should detect
/sbin/udevadm.upgrade and *abort* the initramfs generation.
What I can't figure out is how the linux package was configured at all
under these circumstances: linux-image-2.6.31-14-generic depends on
initramfs-tools, and initramfs-tools depends on udev. So there should
have been no point at which update-initramfs would have been called
while udev was unconfigured. So maybe this isn't a udev bug at all,
but a bug in update-manager.
Here, though, are the relevant bits of /var/log/dpkg.log.
