not a bug

[Mark Hahn]

forgive me for not sending either a bug or patch: I'm trying to find 
a grubby way to do the equivalent of "lilo -R <imagename>".  that is,
set a one-time image to boot, overriding the default.  I find this 
quite useful in testing kernels, and, on the dark side, temporarily
booting a machine into W*nd*ws...

what I need seems almost like the opposite of savedefault,
but would be nice to have avalable from the commandline.

thanks, mark hahn.
