mdadm /boot mirror and sun disklabel corruption

[Fedor Konstantinov <blmink@mink.su>]

Hi, list

I would greatly appreciate if it could be possible to add to the 
installer ability to select mdadm metadata version when creating RAID 
arrays.
Now, when creating mirror for /boot partition (at sun disk slice 0) 
installer uses v1.2 metadata and so it corrupts sun disklabel.
To avoid disklabel corruption, now I have to manually create such 
partition with v0.90 metadata, and ext3 fs in it.

Regards,
Fedor
