Problems with latest live-helper and backports

[Ronny Standtke <ronny.standtke@fhnw.ch>]

Hi all

When I add some backports, the latest git snapshots of live-helper fail:

Here is the added source:
# cat config/chroot_sources/debian-backports.binary
deb http://backports.undebian.org/repositories/backports-other/ ./

When I run the following commands:
# lh config --linux-packages "linux-image-2.6 aufs-modules-2.6"
# lh build

building fails with the following error messages:
...
Get:9 http://cdn.debian.net lenny/main Packages [6911kB]
Fetched 7408kB in 12s (575kB/s)
Reading package lists... Done

P: Begin unmounting /proc...
umount: /tmp/livehelpertest/chroot/proc: device is busy
umount: /tmp/livehelpertest/chroot/proc: device is busy
P: Begin unmounting filesystems...

Checking with lsof reveals that rsyslogd is the culprit:
# lsof | grep chroot/proc
rsyslogd  14186        root   19r      REG        0,3         0
4026531848 /tmp/livehelpertest/chroot/proc/kmsg

So, either rsyslogd from backports needs a fix or live-helper can fix
the problem generally by checking for mounts in the chroot, killing all
processes and umounting before continuing.

Best regards

Ronny
