Well, not all such commands can be expected to do something useful.
Stopping mounts which the system depends on is going to break it, so
trying to "systemctl stop -- -.mount" is rightfully refused already,
while unmounting other things like /dev/pts will just eventually break
your system anyway.

Personally I think that Stephane's second patch was just about the
right compromise:

It is reasonably future-proof (unlike the first patch) and avoids
the problem you mentioned too, i. e. silently not doing operations
while they appear to be successful.

@Lennart: We now have three patches -- could you make an executive
decision which one we take? :-)

Thanks,

Martin
