You loose nothing with this situation. You boot the tape,
then use the RAMDISK kernel to load a miniroot into the swap,
then boot a GENERIC kernel from swap. At least, that's how
"recovery from alternate media" works on the sun3.

It's true that you don't save much space by removing the option,
so I guess its more of a philosophical thing...
