[buildd-tools-devel] Bug#815175: sbuild-update fails to unmount schroots on failure

Package: sbuild
Version: 0.68.0-1
Severity: normal
The sbuild-update(1) commant fails to unmount schroots after
encountering errors. I expected it to gracefully clean up after itself,
unless otherwise specified, upon encountering an error. I've attached a
copy of my schroot.conf.
Here's a transcript showing the issue:
