I've managed to avoid upgrading a kernel up till now. How
tricky is it on
a scale of 1 - 10 for someone slightly above the level of complete incompetence?
If you have some idea of what hardware is in the system (or a .config file hanging aroudn from last time), then it's pretty simple, really. Some people find the kernel-package package in Debian is helpful, but I tend not to use it. I recommend make menuconfig...
After last night, and making a kernel with the IPSec patches in by just typing the right (one) command, I've decided that make-kpkg is lovely. Now all I have to do is switch my firewall box over to Debian. And repair its disk. And ideally find it a monitor which hasn't got 20 second phosphor persistence...
Incidentally, when I've used SysRq I've found it needed enabling with an echo 1 >/proc/sys/kernel/sysrq on boot. Do it. It's invaluable when your machine goes tits up. (Especially when it's a general workhorse machine that everyone uses, with 40G partitions and a strange intermittent kernel bug that makes it impossible to reboot.)

Thanks Ian
That gets my tip of the day vote! Just checked and found that my Eridani Linux 6.3 systems ( Redhat 6.2 update based ) all have that unset.
Presumably it will be the same story for other default RedHat systems.
One more change to default init that's highly recommended...

On an RH/Eridani system, look at /etc/sysctl.conf, and change the line kernel.sysrq = 0
to = 1.
If the line isn't there, add it.
