Main reason is that I'm not sure that, even though I'd expect os-prober to detect other OSes correctly, I doubt that grub-installer would create correct entries for them. If you can test that, then adding os-prober support is of course fine. As you can see in the history of the BR, that is the one part of your changes I was unsure about. > 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. That's not needed. Giuseppe has already taken your changes from the diffs between Debian and Ubuntu sources and I already have commits to our SVN repository prepared based on those (with some mostly mostly minor changes and some additions). What would be useful is if you could check those, which is probably easiest to do after they've been committed. > > Question: how does booting from fakeraid work with e.g. RAID5? > > Reading the bootsector will work fine, but I don't see how grub can > > read its stage files from a RAID5 array. > > As long as the fakeRAID BIOS loads, and grub uses BIOS calls, all will > work.

OK, so that is a case where having real hardware _does_ make a difference and an emulator without the BIOS support cannot be used for testing.
