[Pkg-utopia-maintainers] Bug#859147: Bug#859147: network-manager: restart failure on upgrade

[ydirson at free.fr]

Purged laptop-mode-tools, rebooted, no change.

network-manager is properly started at boot time, service can be stopped, but not started again
afterwards: systemd now has a "(kManager)" child at near-100% CPU.

Found the culprit: I have a broken schroot configuration (talk about pending work and switching to other tasks...), where the
chroot is under my home dir, which gets mounted in the chroot.  Schroot does not detect the loop and
recursively mounts all /home submounts, apparently until a 65535 mountpoint limit

Thus I assume that systemd is attempting to mount something, and not dealing properly with
the error ?
