that would actually be most welcome.

I have just finished changeing all my non boot freebsd-zfs partition types to freebsd-vinum
so as not to confuse the boot loader.

I also disabled my sas controllers exposing the drives in the arrays to the bios as that was
also bloating the initial set of potential targets to boot from.

So having an explicit way of targeting the boot devices would really be cool.

You would propably still need to keep the current default logic when there is no bootme
property set on any bios visible partition.

Greetings
Christian
