Bug Description

After having upgraded my host system to Debian testing (basically from Hardy), the etckeeper/bzr setup in the containers started logging the debug output to /etc/.bzr.log (instead of /root/.bzr.log as before).

"vzctl exec" which is used to execute the command(s) in the OpenVZ container does not properly setup the $HOME variable, but this had been the case before already.
I will have to investigate if "vzctl exec $VZ 'echo $HOME'" has been "/" before upgrading already, or if this is a detail that has changed.

My guess is that vzctl is setting $HOME to /etc now.

It would also be worth checking BZR_HOME and BZR_LOG.

afaics bzr just uses whichever of those variables are set, so I'm fairly sure there's something outside of bzr causing this; please reopen if you're sure it's not.

Maybe there's something different between container 123 and 125?

This is not set in env - I have posted the quite minimal "env" output IIRC.

It is caused by $HOME - I had patched vzctl previously to use "/root"
instead of "/", and done so now again (attached):

TERM=linux
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
PWD=/
SHLVL=1
HOME=/root
_=/usr/bin/env
Bazaar (bzr) 2.1.2
  Python interpreter: /usr/bin/python 2.5.2
  Python standard library: /usr/lib/python2.5
  Platform: Linux-2.6.32-5-openvz-amd64-i686-with-debian-lenny-sid
  bzrlib: /usr/lib/python2.5/site-packages/bzrlib
  Bazaar configuration: /root/.bazaar
  Bazaar log file: /root/.bzr.log

However, if I remember correctly, Bazaar was using "HOME=/" previously
(and therefore logging to /), while it now discards HOME=/ and
apparently logs to the current working directory.

I am attaching the debdiff for reference.

Invalid for bzr: it has been like this from the beginning, according to my comment in the vzctl bug (http://bugzilla.openvz.org/show_bug.cgi?id=942#c0).
