- * base_device.c
- *
- * Return the "base device" given a particular device; this is used to
- * assure that we only fsck one partition on a particular drive at any
- * one time.  Otherwise, the disk heads will be seeking all over the
- * place.  If the base device can not be determined, return NULL.
- * 
- * The base_device() function returns an allocated string which must
- * be freed.
