[buildd-tools-devel] Bug#567932: Bug#567932: schroot: chroot failed, cleaned up my host /etc

Wed Feb 17 22:41:17 UTC 2010

Hi Roger,

Here are the only files which were modified. I have since put in the
versions from 1.4.0-1 and customized those and schroot is working fine.

# schroot chroot definitions.
# See schroot.conf(5) for complete documentation of the file format.
#
# Please take note that you should not add untrusted users to
# root-groups, because they will essentially have full root access
# to your system.  They will only have root access inside the chroot,
# but that's enough to cause malicious damage.
#
# The following lines are examples only.  Uncomment and alter them to
# customise schroot for your needs, or create a new entry from scratch.
