[CentOS] Kickstart mdraid on two disks, from usb key detected as sda instead of sdc...

Hi,

I am trying to adapt my kickstart usb key to optionally auto-setup mdraid on 

two disks...  But I have one server that keeps attaching the usb key to sda 

instead of sdc...
My kickstart creates the raid devices on sdb and sdc partitions; but then I 

expect it not to work once the key is unplugged and the disks fall back to 

sda and sdb...


Can I just modify mdadm.conf at the end, just before rebooting?

What about grub?


Thx,
JD
