 * For ufs 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
