Hi,

When migrating to a larger disk on my AlphaPC 164SX yesterday,
I've found that the standard bsdlabel(8) layout is not understood
by the Alpha bootblocks.  By "standard" I mean that the `a'
partition holding the root file system starts at offset 16.

I did "bsdlabel -B -w da1 auto", then split the auto-created
`a' partition (that starts from offset 16) to /, /usr, /tmp,
and /var, then used newfs/mount/dump/restore to copy file
systems to a new location.

After a reboot, bootblocks complained that /boot/loader was
not found.

I re-edited the label, and changed the partition `a' to start
=66rom offset 0, doing another newfs/mount/dump/restore cycle,
this resulted in a mountable disk.

This is with 6.0-CURRENT...


Cheers,
