Ugo, hmmmm at first i was saying to myself, well sudo said that he knew about the riserfs support in centosplus directory but that he cant do that with kickstart. Now i see what you are talking about, use kickstart and then do a yum update kernel(for riserfs) and then reboot. ah i see said the blind man to the deaf man.
Which is why I _never_ make my root (/) filesystem anything but Ext3. I can always use basically any kernel 2.2 or later Ext2 implementation to read it.
Currently, we use ext3 for all file systems except for the DATA partition(s) which is where our critical data lives. The DATA partition(s) hold about 15-20 million files.
So there should be no problem upgrading using the CD, then update the kernel to centosplus', then reboot and mount your data partitions using ReiserFS?
The only downtime would be the yum update + reboot. You could probably do that on many machines at a time, maybe using a post-install script or using something like pssh.
