This doesn't actually work in my tests, the ExecStop= is needed (tested with systemd 219). I was quite surprised that this fixed a lot more than just the hangs on unmounting network file systems. I also got reports that other vague shutdown hangs now disappeared (https://launchpad.net/bugs/1427672) and that shutdown hangs with libvirt's virbr0-nic interfaces are now gone as well. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dbus in Ubuntu. https://bugs.launchpad.net/bugs/1438612 Title: remote file systems hang on shutdown, D-BUS stops too early Status in D-Bus: Confirmed Status in dbus package in Ubuntu: Fix Released Bug description: (part of bug 1431774). During shutdown, D-Bus stops too early. In particular, it stops before NetworkManager and remote-fs.target, so that any network unmount will cause errors and hang the boot. This can be seen with $ journalctl -b -1 | egrep 'Stop.*(D-Bus|Network M|Remote F)' Mär 30 19:05:19 donald systemd[1]: Stopping D-Bus System Message Bus...

A quick workaround is to add After=dbus.service to /lib/systemd/system/NetworkManager.service's [Unit] section, but this should be fixed in a more general fashion.
