[Pkg-systemd-maintainers] Bug#726375: schroot: Fails during umount on system booted with systemd

[Daniel Schepler]

Package: schroot
Version: 1.6.5-1+b1
Severity: normal
X-Debbugs-CC: systemd at packages.debian.org

So, I just decided I'd try out systemd.  It booted my system without any
problems, but I soon discovered that the x32 buildd I'm running on it isn't
working properly.  For an example of what triggers build failures:

buildd at frobozz:~$ schroot -c sid-x32-sbuild -u root -d /root -- apt-get update
