O.K., I booted GNOME and searched for some way to accomplish this, but couldn't find any. (The closest I got was the
gnome-session-properties command that lets you change the
startup scripts, and save your session when you log out so any program(s) you had running will be restarted.
Have you tried writing a
shutdown script that replaces the
/sbin/shutdown command? Something like this:
Code:
$ cat /usr/local/bin/shutdown
#!/bin/bash
sudo umount --all --force --type cifs
exec sudo /sbin/shutdown $*
which I wrote when my system was hanging during shutdown waiting for the Window$ system to respond to an
umount command. (I had originally changed the symlink of
shutdown in
/sbin to point to that script, but often when
systemd gets updated, the symlink is reset.)
Note that I have "Unbuntized" my
sudo so I don't need to enter a password. (
Not recommended for any system needing security.)
I haven't actually tried that script under GNOME, but it, or something like it, might work for you.
