[buildd-tools-devel] Bug#866006: sbuild-createchroot should abort if schroot --list --all-source-chroots fails

[Johannes Schauer]

Source: sbuild
Severity: normal

sbuild-createchroot attempts to check the output of $(schroot --list
--all-source-chroots) to make sure that the to be created chroot doesn't
exist already. In addition to checking the output of the command, it
should also check the exit code of the command because the command might
fail with a non zero exit status. This happens for example when there
exists multiple chroots with the same name. In that case,
sbuild-createchroot should abort.
