[CentOS] Autodetecing RAID members upon boot... need to update initrd?

>In the future, when upgrading the kernel, will future initrd's be built with my current modules or will I have to manually create new initrd's after each update? 

Good question that I would love to know as well. I thought /etc/sysconfig/mkinitrd handled
this, but not ripping apart the srpm of a new kernel, I don’t really know if it bothers doing
making the initrd.
