	struct lfs in ufs/lfs.h claims to be 512 bytes long.  However, since
	the m68k compiler seems to be content to align long-words to word 
	addresses, the structure is only 510 bytes long.  What's it like on
	a 386 or Alpha?
	Get newlfs, put it under gdb and do a sizeof(struct lfs).
	I have a couple of ideas but I'm not sure they will work on all achitectures.
