While we're throwing out ideas... :-)
I've always had on my wishlist a way to optionaly have /kernel
"expire" in such a way that if the timestamp on /kernel is older
than, say, 10 minutes, then boot from /kernel.old.
The option to "testboot" /kernel would be enormously useful if you
don't have physical access to a machine and the newly installed
kernel for some reason doesn't boot. Just have someone hit the
reset button 10 minutes later.
I think the only real hacking needed would be to make /boot/loader
aware of the CMOS clock. It's been something I've been looking to
do, just haven't gotten around to it.
