Bug#501306: confirmation

[Martin Hansen]

I just want to confirm, that the problem is in difference in device mapping in 
the installer and in final system, i got the exact same error.
removing devicemap file, and thereby triggering update-grub to regenerate with 
call to grub, solved the problem.
making update-grub regenerate devicemap every time (including deleting the old 
one)  would have solved my problem, but might create other problems. 

But just an error message telling me that it was the convert functions call to 
grup-probe that failed, and I should take a look at the device map, would 
have saved me a lot of time.

I think the right solution is to have the installer trigger a regenerate on 
final system after first boot. or make the installer map devices the same way 
as final system (maybe more difficult)
