# check_rootdir - 11/18/2003 - Patch from Ryan Bradetich:
#        * Add an ownership check for the root directory.
#        * Add documentation for the ownership check.
#        * Remove the mode variable (no longer used).
#        * Comment updates.
#        * Remove the check to make sure / is a directory.
# check_rootdir - 03/21/2005 - jfs
#        Do not warn on the inode if the root filesystem is not ext2|3
