Now that we’re installing udisks, the symptoms are slightly different, but basically the net result is the same. I suspect that pkill gdm3 in udev-watchdog-wrapper is causing systemd to want to restart the gdm3 service. We could try to remove Restart=always from its unit file, and see what happens.

Indeed, commenting out the two lines that start with Restart in /lib/systemd/system/gdm.service avoids the “back to the Greeter” effect. But I see lots of “SQUASHFS error”, and the system seems to be frozen. Next step: add basic debugging to do_stop so that we know at which point it fails.

Removing the test for “systemd is pid 1 and is currently running a reboot job” in /etc/init.d/kexec-load seems to fix emergency shutdown. Hopefully it doesn’t break regular shutdown.

Pushed a fix, that seems to work in a few cases. Next steps: test more cases.

Now works fine. What’s displayed on the screen may be a bit less nice than what we had in Wheezy, but it’ll do fine at least for the time being.
