Public bug reported:
Binary package hint: util-linux
Bug 711799 exposed this behaviour of mount. It does a number of stupid things:
1. It does not notice that the file system is exclusively open
2. It does not notice that the file system is marked unclean
Furthermore, mount shows it lack of intelligence by trying to mount it,
1. despite of the facts above
2. not timing out when it doesn't succeed
3. ignoring all signals trying to make mount exit gracefully
At least it seems, that mount checks solely if the file system is in
/proc/mounts, and if it isn't, it goes through irrespective of anything
else; if need be hanging itself.
(I filed the bug on amd64, though the behaviour was noticed on 32-bit.
It remains to be seen if the source code is identical.)
