IOW, think network filesystems.
Can't I just not do the tests when the filesystem is a network fs? I don't
think it should be a problem for disk filesystems on network-attached storage.
it's not trivial to detect if a filesystem is local or network (you would have
to do calls to figure out what filesystem you are on, then have a list to define
what's local and what's remote, that list would become out of date as new
filesystems are added)
