Well, from my point of view is it mistake that getopt() supports
something like $POSIXLY_CORRECT. It's application, not library, who
has to control input/command line parsing.
The shared libraries should be sensitive only to environment
variables which control library private stuff or things which are
really transparent to applications (LANG=...).

The mount helpers command line is out documented API. I don't see a
way how to change it without break the compatibility between mount(8)
and mount.<type> helpers.

Don't assume that everyone uses getopt() from glibc. You can
use "if (strcmp(argv[], ...))" to parse command line arguments.
I think it would be better to remove POSIXLY_CORRECT from
mount.<type> environment in mount(8) before we execute the helper.
