Hi Vapier:

Currently, I installed rootfs on RAID5 array by using mdadm and lvm.
On shutting down, I notice that the system produced the following
error message:

	mdadm: fail to stop array /dev/md3: Device or resource busy

After searching the internet, I found that this is because the rootfs
on the RAID. With rootfs on RAID, we can't umount the filesystem on
the RAID, so we can't stop this RAID. 

In fact, there is no need to stop the RAID explicitly on shutdown
because the kernel will stop it internally and automatically!

So my suggestion is that don't add the raid-stop.sh addon in the
package sys-fs/mdadm, which is maintained by you if I am not wrong.
