My pool, using p0 devices, does currently mount at boot. This is using the
p0 devices in /dev/dsk, not symlinks in a directory (those have been
deleted).
This does seem like it might indicate that importing the devices changed
something on disk - I'm not sure what, but something that has caused it to
know that it should use the p0 devices rather than s2 or s8. I have no idea
whether this would affect ability to import in BSD. It does not seem like it
should, intuitively, but I don't have much basis in actual knowledge of the
inner workings to say that - you shouldn't take my word for it.
As for partition tables, everything seems to be working happily without
them. I'd still like to know from somebody more knowledgeable about what I
might lose, not having them, but I haven't run into any issues yet.
