-Under SunOS 4.0 at least, I believe the easiest way to do
-this is to stat the file, then compare the st_dev value
-with the st_dev value gotten from stat'ing all the mount
-points.  Use the getmntent(3) family to examine /etc/mtab
-to find out what has been mounted where.  When the st_devs
-match you can determine whether the file is NFS or not.

Wouldn't it be easier to access the file then see whether
the access time had been updated?
