Bug#610525: lvremove hangs late_command

[Andreas Unterkircher <unki@netshadow.at>]

Hi,

We are hitting this too now after years using lvremove in  
late_command. Also while Squeeze was testing we were using this  
without any problem.

Anyway problem seems to be that the late_command is invoked chrooted  
in /target.

While calling lvremove from the debian-installer rootfs works, calling  
lvremove in the chroot immediately hangs waiting for some lock.  
CTRL+C'ing it leads to the message

CTRL-c detected: giving up waiting for lock
/var/lock/lvm/V_$vgname: flock failed: Interrupted system call
Can't get lock for $vgname
Skipping volume group $vgname

/proc and /sys are mounted.
Maybe because device-mapper isn't started yet or so...?
