Comment 7 for bug 392510

After reading the bug more deeply Giuseppe states that it does invoke the update-initramfs but only on the latest kernel.

The thing I dont understand is why you would want to use mdadm and dmraid together, each provides the same functionality although dmraid allows you to boot off of RAIDs other than RAID1. Mdadm and Dmraid can only cause issues when used together as they are both fighting to do the same thing.

I'm fairly sure on my last install from the livecd I had to install dmraid seperately to starting ubiquity, mind you it may just be that ubiquity installs it anyway and I was being inpatient.
