A question about ZFS built-in SMB

[krad]

"but it's the 3rd party nfs server that actually does the sharing."

You are misrepresenting here a little as the nfs server in freebsd is a
core part of the OS, and not some third party addon. It has a few userland
daemons that can be used however its mostly in kernel. Linux is pretty much
the same as well. However the key difference between Freebsd and linux is
that because no mainstream linux distro ships with production grade
zfsonlinux there has been little work on the userland integration
in comparison to solaris, so stuff like the auto configuration of nfs isn't
always there yet. Samba is a 3rd part product for freebsd and linux though
explaining why there isn't any auto configuration.

freebsd
# kldstat -v | grep nfs
                208 nfslockd
                158 nfscommon
                207 nfssvc
                161 nfsd
                159 nfs
                179 acl_nfs4
                160 nfscl
                206 nfslock

Linux

[cscott at SL1VSIKS ~]$ lsmod | grep nfs
nfsd                  299008  13
auth_rpcgss            61440  1 nfsd
