Well, you were rather directly, very assertively, and not totally
correctly, disputing a prior poster:

He correctly said it was *able* to do so, you said it couldn't do so
(i.e. it doesn't remember, and it always boots the default kernel).
If you'd said it doesn't normally do that, I'd have agreed with you, but
your prior reply was rather misleading. Anybody who might have wanted
to do what I'd described, might well have took what you said at face
value, and not looked any further to see if it could have been done.

It's not difficult to do. And unless you never prune out all your prior
kernels (which is bad management), it's not a lot of work. The manual
isn't too bad describing this, and I certainly would read a manual for
something if I was considering customising my PC to do something. And I
do think it *is* intuitive that a reboot actually reboots your PC using
the same system that you were already using, in certain circumstances
(e.g. multiboot systems, or systems used by other people - where they'd
expect a reboot to allow them to carry on doing what they were doing
before, and not have to worry about anything special that you might have
done before they started using the PC).

Not sure you really want an answer to that on a list which may well have
a huge number of participants...
