Update from 8.0.94 to Shrike: Software RAID 5 has to be erased?

["Agon S. Buchholz" <asb kefk net>]

Hi,

I'm just trying to update a Phoebe 8.0.94 system with a Software RAID 
Level 5 array (ext3, _not_ ReiserFS) to Shrike. The array works fine, 
Psyhce does also.

When I select "upgrade an existing system", the installer tells me 
something like: "The partition table on drive hde is not readable [...] 
and has to be initialized [...]".

The system boots from a separate drive, I'm _not_ booting from RAID and 
I don't see what the installer is trying to mess around with drive hde 
(which is part of the array).

Is there any way to _safely_ update a Software RAID system, or do I have 
to stick with Phoebe forever?

Greetings, -asb
