Should we encourage folks to just configure their VMs to use xbd?  I hope some day that the system will just report "da" devices, so the ada name may change again.  We could also suggest specifying SCSI disks in the VM config since I don't think "da" will ever change.

I've never seen a kernel build take 2 hours, much less 2 hours *longer*.  Are you talking about buildworld?  It would be interesting to know your results building stable/9 sources in your 10 environment to see if this is just due to "build bloat" or a true performance regression.
