Package: silo
Version: Version: 1.4.14+git20120226-1
Severity: normal
I have a Sunfire V210 with an mdadm RAID1 /boot which could not install
silo. I suspect this was due to the RAID slot numbers, as recreating an
otherwise identical RAID let Silo move beyond that... to "File systems
other than ext2, ext3, ufs and romfs not yet supported". Finally
installing Silo seemed to require the moving mdadm metadata to the end
(not sure if this counts as a bug too).
I have access to another V210 to attempt to reproduce if it would help.
From a rescue shell:

## The only way to have silo install was to recreate the RAID as:
mdadm --create /dev/md0 -n2 -x0 -l1 -e 1.0 /dev/sda1 /dev/sdb1
