TMPFS was not in the first release of 4.0. It was introduced to boost the performance of diskless clients which no longer had the old network disk for their root file systems and hence /tmp was now over NFS.
Whether there was a patch that brought it back into 4.0 I don't recall but I don't think so. 4.0.1 would have been the first release that actually had it. --chris -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
