Afaik "yum update kernel" ensures there are always two kernels

there is an issue with the new one you can still boot the old one and
have an operational system to fix the issue.
Exactly. It is very bad practice to only keep one working kernel on a
system, even for those you term "non-advanced" users. If that kernel
gets toasted (and it can happen to anyone) you have no alternate to
boot from. As explained above FC always keeps at least two kernels,
and on my systems I tend to up this to three or even four.
Also, I don't think simply letting the suspend "tag" the kernel that
was used, so you "know" which it is in the grub menu is any better.
How is it tagged ? Say the default one is altered - Can you honestly
say that every time you boot your machine you can recall if the last
time it was turned off it was suspended or shutdown ? I doubt I can.
What if it wasn't you who did it last time.... The user can still use
a different kernel to the "default" one, innocently, and toast their
system.
No - I still say whatever system is used it must guard against this -
It must not be possible to choose the wrong kernel after a suspend. I
don't know it there is some way to maintain this safeguard and still
allow people to boot directly to windows ? If there is great, but I
think maintaining this safety is much more important than some "fast
windows" boot. After all, you can still get to windows with things how
they are, it just requires a proper reboot.
Chris
what about storing the kernel version in the suspend image and refuse to
boot if it does not match the running kernel?
