Bug#948710: openssh-server: Fail to upgrade "ssh.service: Unit -.mount is masked"

[Phillip Susi]

I brought this up on systemd-devel the other day and Lennart agreed that
it is a bug in systemd that it refuses to start services that depend on
masked mount units when the mount is active.  He advised me to file a
bug report on github, but github insisted on emailing me before allowing
me to log in even though I know my login and password, and they seem to
still have my no longer existing ubuntu email address, and so I am
locked out.  Their contact us page also does not seem to work nor have
they replied to my attempts to email support@, so I am unable to file
the upstream bug.

He also advised that gparted should be using a bsd file lock instead of
masking mount units.  Curtis Gedack wasn't sure about making the change
at least for the upcoming release of gparted.  Perhaps after that.
