38 * File system table, see fstab(5).
40 * Used by dump, mount, umount, swapon, fsck, df, ...
42 * For ufs fs_spec field is the block special name. Programs that want to
43 * use the character special name must create that name by prepending a 'r'
44 * after the right most slash. Quota files are always named "quotas", so
45 * if type is "rq", then use concatenation of fs_file and "quotas" to locate
46 * quota file.
