[Buildd-tools-devel] Bug#426416: schroot: Cannot umount "" on old chroots

[Federico Di Gregorio]

Package: schroot
Version: 1.1.3-1
Severity: normal
Tags: patch

Some days ago schroot begun to report the following error

E: sid32-61f1f291-86fe-40b1-b328-0de469e9ff98: Chroot setup failed:
stage=setup-stop
 sid32-61f1f291-86fe-40b1-b328-0de469e9ff98Cannot umount ""

when ending old sessions after a reboot done with open sessions. The following
one-line patch fixes the problem by not trying to umount sessions that don't
have anything mounted.

Hope this helps,
