[CentOS-devel] CentOS mkinitrd support for dmraid

Hello,

Here is a patch to mkinitrd that enables dmraid initialization during init.

I developed it to enable proper initialization of LVM partitions hosted on dmraid based software RAID.

dmraid initrd initialization can be optionally turned off by passing --omit-dmraid command line key to mkinitrd.

My changes are tested on CentOS 4.1 2.6.9-11.EL kernel.

Hopefully this may be useful to people with similar software/hardware configurations.

Can someone suggest/clarify if there is anything else I could/should do to make this patch helpful to as many people as possible and ideally make it part of CentOS distribution?

Thank you very much, Hovhannes Tumanyan
