That is correct: Since umountnfs is never run on boot it is not stopped
on shutdown, that's why explicitly masking was not necessary. Sorry for
not being precise in that regard.

This is all pretty tricky. For now we explictly use the if-up.d
mechanism in favor of mounting remote file systems in systemd. I don't
remember all the details anymore but I know this needs some more work to
be done properly.
