Package: lvm2
Not sure if the problem here is lvm2 or initramfs-tools. On an IBM x330
box, I recently attempted to install lenny with an lvm root. After the
installer rebooted, the lvm pvs/vgs/lvs were not detected, and thus the
machine didn't boot without intervention.
It appears as though the physical drives are not getting detected until
after scripts/local-top/lvm2 is run:

Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/mapper/ibm--09-root does not exist. Dropping to a shell!

--CUT--
(/dev/sda2 is the pv with the vg that contains the root lv on it, in
this case)
If I pvscan and then vgchange manually afterwards, they are picked up
fine. Similarly, if, during the install process (e.g. via late_command),
I put a "sleep 5" in scripts/local-top/00lvm and regenerate the
initramfs, then it works fine.
I don't know if there's something lvm2 can do about this... or does
initramfs-tools need another `udevadm settle' before running the
local-top scripts or something?

the release notes prominently document the rootdelay
bootparam it is exactly for such circumstances.
just use rootdelay=12 or such.
