[buildd-tools-devel] Bug#666274: schroot complains about unknow source-root-groups config entry

[Raphaël Hertzog]

Package: schroot
Version: 1.4.25-1
Severity: minor

I have this warning about a chroot I setup:
$ LANG=C schroot -c squeeze -p
W: line 7 [sid-test]: Unknown key 'source-root-groups' used
I: This option may be present in a newer version

However man schroot.conf clearly documents this key:

source-root-users=user1,user2,...
      A comma-separated list of users which are allowed password-less root  access
      to  the  source  chroot.  If empty or omitted, no users will be allowed root
      access without a password (but if a user is in users, they may  gain  access
      with  a  password).   This  will  become the root-users option in the source
      chroot.  See the section “Security” below.

source-root-groups=group1,group2,...
      A comma-separated list of groups which are allowed password-less root access
      to  the  source  chroot.  If empty or omitted, no users will be allowed root
      access without a password (but if a user's group is in groups, they may gain
      access  with  a  password).   This will become the root-groups option in the
      source chroot.  See the section “Security” below.

After investigation, it turns out that this specific chroot was
lacking my usual "union-type=aufs" entry... I believe that the error
message should be improved to point out the real underlying problem
because claiming that the key is unknown is misleading.
