Because they survive kernel updates transparently and you can run the distro kernel, there will be no "waiting" for each kernel update.
That is indeed what I need, I use ieee1394, raw1394 and sbp2 to access my 2tb firewire external drive that is used for backup rotation.
I will try that on monday.
Yum shouldn't have deleted your running kernel in the update. It should just be a matter of changing the default to boot in the grub config if you want to run the old one a while longer.
No, it didn't, but on reboot, it booted the non-centosplus kernel, the one that was more upto date...
