[Nagiosplug-devel] check_disk.c HEAD without -d parameters

I don't understand the /dev/???? argument. Why would you specify a file to
check? I know a "df /dev/file" will return information for the /dev
filesystem, but check_disk doesn't try to work out which filesystem a file
belongs to, so currently "check_disk -p /dev/file" returns a disk not found.
I think check_disk should only check disks/partitions/filesystems and not
individual files.

I guess there could be confusion if there was a device called /var and a
filesystem called /var, but this would never be the case as they would be
unique locations under /.

However, I agree a Nagios administrator should know the difference. If -d is
to be used, I think it should be done for the 1.4 release as we are already
breaking current syntax (eg, -p "/ /var" no longer works - must be -p / -p
