Hello,
I know that NetBSD can have its FFS root residing on a software RAID1 using RAIDframe, and that root on ZFS is possible with the help of a separate FFS boot partition, but I'm wondering whether instead of a single partition it's also possible to use a ZFS mirror (or any other kind of ZFS RAID) as a root volume... I don't see why it wouldn't, but I couldn't find any mention of someone having ever tried it. Is anyone using such a setup?
