Hello,
This is a consolidated list of ZFS pool and filesystem versions, along
with the builds and systems they are found in. It is based on multiple
online sources. Some of you may find it useful in figuring out where
things are at across the spectrum of systems supporting ZFS including
FreeBSD and FUSE. At the end of this message there is a list of the
builds OpenSolaris releases and some OpenSolaris derivatives are based
on. The list is sort-of but not strictly comma delimited, and of course
may contain errata.
