Ah, that's right, it's the centosplus repo that contains that stuff.
At least I know now that I can use standard means that are really 
updateable via 'yum update' and it's only a matter of a) enabling the 
repo centosplus, b) installing the kernel, c) rebooting and that's it. Cool.

No objections to using the centosplus kernel in production environments?

Indeed, I already had some poweroffs and I think I can be lucky that my 
3ware 9550SX-4LP has a cache battery. Knock-on-wood, there wasn't any 
severe catastrophe yet.

Another question: Can I also find 'quota' in the standard kernel?
That would make the thing perfect. :)

Thanx for your answers
