mount: "nofail" and already mounted devices?

[Stanislav Brabec <sbrabec@suse.cz>]

Attempting to mount of already mounted devices is a common situation in
many scripts. There is no easy way to detect it in the current mount
implementation.

One of our users complains that this situation is not covered by
"nofail" mount option. ("nofail" does exactly what the documentation
describes and nothing more.)

Would be acceptable a patch that adds "already mounted" to "nofail"?

If not, what would be the best way of enabling this feature for mounting
a single device? (It already exists in mount, but it is usable only with
"mount -a".)

- Add another mount option, e. g. mountednofail or mountedok
- Make possible to use "-a" with further arguments.
- Add new option, e. g. "-A".
and/or
- New result code, e. g. 33 instead of 32. (As it can not suppress the
error message, it is well usable only as an addition to above.)
