How does MAAS pick which volume to boot from?

[Andres Rodriguez]

HI Daniel,

It seems that you would need to configure the disk where you want to
install "/" as the first boot disk on the BIOS, provided that the OS (nor
MAAS) has a way to determine which is the disk the machine will be booting
from.

That said, this issue no longer exists on machines that use EFI, provided
that it will automatically detect from which disk to boot from.
