That's true and as it stands, licensing issues mean it won't be a
kernel filesystem in linux. However, ZFS works fine using the fuse
module. I use ZFS as a common filesystem for backup. The only issue is
the differing versions of ZFS and which is used to create the pool.

Sorry, I should learn to read. Afaik, ufs2 is read only under linux,
write support is available but the module isn't built by default and
it's listed as 'dangerous'.
