From some earlier post I gathered that biosdisk part_msdos ext2 were
auto-detected anyway and not necessary. Could somebody check whether they are
necessary are not?

I'm ok with dropping serial; is dropping raid necessary as well? Does it in fact
mean that one cannot combine raid and lvm?

Could somebody send me their /boot/grub/device.map with LVM? As far as I
understand device2grub just parses this file, so probably it just requires a bit
of tweaking.

I'd be more than happy to make the grub2 stuff of experimental (and actually
also mainline FAI) finally work; it's just that I don't have any system running
grub2 and got not hosts to do any testing. I'm therefor relying on your help.

Best,
Michael
