bug#77086: Filesystems not unmounted on reboot

[Ian Eure]

Hi all,

Here’s a less dead link to the config for my system exhibiting the 
problem: https://paste.debian.net/1366307/

I set it to never expire this time.

The FS stuff is very pedestrian, it’s more or less what the 
graphical installer generates, since that’s how I installed that 
system.

Thanks,
 -- Ian
