Package: schroot
Invoking /bin/kill on processes fails if the process already
quit by itself while the schroot shutdown runs. Because of "set -e"
this causes the whole shutdown to fail.
I have seen this occasionally in a nightly testing setup involving
a D-Bus session: when the D-Bus daemon stops, all other processes
depending on it also shut down automatically, with or without being
killed.
Attached a patch which wraps kill in a function which merely logs
the problem instead of aborting.

Closes: 645223 656239
Changes:
schroot (1.4.24-1) unstable; urgency=low
.
* New upstream stable release.
* Add multiarch support. Backported from schroot 1.5.1.
* Use debhelper 9 and dh using compat level 9.
* Use Standards-Version 3.9.2.
* Build-Depend upon groff-base for soelim.
* Support for zip file archives has been removed. zip was not able
to archive named pipes and device nodes, and so was not usable
for chroot archival.
* Don't Suggest unzip now zip is not a supported archive
format.
* Correct race condition in 15killprocs (Closes: #645223). Thanks to
Patrick Ohly for this patch.
* Fix name lookup issue causing FTBFS with GCC 4.7 (Closes: #656239).
Thanks to Ralf Corsépius for this patch.
