Hi! I have an software raid installation (md_dX type) and i am wondering

Yep, as long as you are using the stock kernels, you should be safe. I
use linux raid a lot and haven't had a problem. Just yum update and
you're ready to go (if you upgrade from/to minor version be sure to
read the release notes and erratas).
Thanks! Yes i am using the stock kernels and i asked because i use an
modified mkinitrd (for raid md_dX type suport) and wanted to be sure
that initrd is rebuilt at kernel update time.

Thanks,

Ouch, the fact that you were using a modified initrd was not obvious
to me from your 1st post.
I dont know if centos does this automatically for you. Maybe it's
safer to create a new mkinitrd after the kernel has installed.
Now i can say that the kernel update recreate at install/update time the initrd so i didn't had any king of problem with this. (of course, having an modified mkinitrd i have in yum.conf :: exclude=mkinitrd*)
