I have set the sharenfs property to 'YES" on the /usr/obj and /usr/src data sets. The ZFS filesystem handles NFS shares internally from the documenation. In any event, this is how my system has successfuly been doing NFS for nearly 2 years without any issues. A client should be able to read and not write to both /usr/src and /usr/obj to be able to installworld and installkernel and have all mergemaster writes confined to a local /var/tmp/temproot. My /etc/rc.conf doesn't have any flags for mountd. It is only a "YES" to enable. Tom -- Public Keys: PGP KeyID = 0x5F22FDC1 GnuPG KeyID = 0x620836CF
