 * File system table, see fstab(5).

 * Used by dump, mount, umount, swapon, fsck, df, ...
 *
 * The fs_spec field is the block special name.  Programs that want to use
 * the character special name must create that name by prepending a 'r'
 * after the right most slash.  Quota files are always named "quotas", so
 * if type is "rq", then use concatenation of fs_file and "quotas" to locate
 * quota file.
