Enable proper boot from SAN

Hi!

It  would be greate to have an easy way to boot from a SAN attached disk drive clone (As EMC's  BC or SRDF).

Currently, If I wish to boot a system in a DR site,  I need to reconfigure the initial ramdisk with the 

cloned disk's id in order to get the kenrel to boot properly and locate the boot partition.

It would be greate if the system could use the attached drive and (the one  used to load the kernel),

withount the need for manual initeamfs image creation perior to booting on a cloned disk.

Thanks!
