Summary: check_disk reports disk usage on bind mounted volumes

Initial Comment:
The check disk usage reports disk usage on bind mounted filesystems when specifying local only filesystems.
This in itself isn't a problem but the problem comes when the filesystem being bind mounted is not a local filesystem
I'm using the latest version of the nagios plugins (1.14).

I'm submitted a patch to check disk that allows excluding of partitions that match certain mount options.

Message:
I've noticed that on RHEL4 systems the bind mounts are not set as
filesystem type "none", and are still displayed. So I've added in another
macro to mountlist.c to fix this and check for a bind mounted option, and
set it as a dummy filesystem. I've attached the patch.

Message:
Okay, I've gotten to the bottom of it. There is an almost unsed static
variable in the check_disk plugin which is used to display or not display
dummy filesystems (like proc etc). So, setting that to disabled, everything
works as expected, and bind filesystesm (which show up as type "none") dont
get displayed anymore.
