Stupidity in kernel upgrades

[dmaze]

I figured I'd upgrade the kernel on washington-street-elevated (my work desktop) to try to get around some NFS performance issues and maybe avoid the most recent local-root exploit. So from SIPB, remotely logged in, I used rpm to update the kernel RPM, and rebooted. Shockingly, it didn't work. I realized when I couldn't ping wse later that I had kind of forgotten the basics of Linux kernel updates ("rerun lilo, dumbass"); what I wound up with was the old kernel with no modules, which was pretty useless. It only took half an hour or so of fighting with that and the NVidia display driver module this morning to get everything back in working shape. But really, I should know better than to screw things up like this.

This is a result of being used to debian, which gets it right? :-)

That, and being used to GRUB, where you don't need to reinstall the MBR every time you change something.
