I have noticed the same thing.  The problem appears to be that NetBSD
does something to the disklabel which makes Solaris format(8) not think
it is a valid disklabel.  This is the only problem I have found as you
can still mount Solaris partitions from Solaris8 and otherwise generally
use it as normal.

See above.  I don't know about sharing filesystems - ie using sd0g for
both Solaris & NetBSD.
