Here's my /sbin/installkernel and assosiated bits that generates a boot
menu out of the available kernel images.
Just hacked this up tonight to no guarantees about it's
stablity/usefulness on any system other than mine.
Hope it is of use to someone.
BTW, I'm calling it it BootGen unless the name has been used by someone
else already.
