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
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.
man 8 nextboot is in order.
