Probably. The real question is: is there a sane way to filter mount notifications so that systemd receives only those which it is interested in, rather than the tens of thousands that for example autofs is managing and has nothing to do with systemd? Is there a specific mountpoint or mountpoints that systemd is waiting for? How exactly does this work? Thanks, Miklos
