So far, I have a patch to allow os-prober to find other OSs on dmraid devices, but nothing for grub-installer yet, as I have been trying to track down why grub-installer wasn't using os-prober's output for other OSs. > I was a bit miffed at first when Giuseppe came up with your patches, but > that lessened somewhat when I saw they were recent.

I understand, and won't make any excuses about not contacting the installer team. As for partman et al, Colin was able to point me in the right direction. > We're currently still waiting for Otavio to discuss the changes with the > release team and give the go-ahead.

Ok, I'll go into detail where necessary later in this mail, but I will shortly file bugs against all d-i packages I've touched, with patches attached. > On Monday 08 September 2008, Luke Yelavich wrote: > > as well as making any changes I make for Ubuntu available for Debian now > > and in the future. > > Please consider - at least when it comes to changes in the installer > itself - to work directly in the Debian SVN repository.

Agreed, and here on in I will do so, as I want to help you guys get this stuff working for Lenny. > I'm quite sad to see the diff growing now that Colin Watson is less active > when it comes to D-I. I can't speak for Colin, but given that I may have to do Ubuntu merges for some of the d-i packages next cycle, I'll see what I can do to push some changes back to Debian. > > I am also happy to test on real hardware, as I have a few PCI cards, as > > well as a recent intel ICH9 board that I can test such configurations > > as RAID 5, and possibly RAID10/01 if desired. > > That would be great. > > Question: how does booting from fakeraid work with e.g. RAID5?

The BIOS sets everything up so that grub simply sees things as an ordinary disk. No different to how booting from raid0 on fakeraid works.
