That was clear to me already, because of the error message (two
steps later in d-i).  I just went back into fdisk and changed it.

Do I need to edit /etc/raidtab.conf or any other file?
If so, does d-i help there?

Yes, thanks for the hint.  Anyway, if the md/raid stuff becomes
part of d-i, there should be a step-by-step intro in the d-i
manual, esp. for people who are new to mdadm and friends.

I will try that, thanks.

No, not really a problem, but it would be nice to use 2.6 in d-i,
if one is going for 2.6 anyway.  If there are problems with 2.6
they show up immediately, which might be better or not.

Thanks for your help!

One remaining question: Does anybody know whether the md/raid
stuff is/will be included into "official" d-i?  Plans?

Cheers, WB
