I also have been using nullfs (since Jun 30 2001) on a number of systems (from 4.3-> 4.8) including my main workstation and multiuser servers. The mounts are rw. FreeBSD dt.home 4.8-STABLE FreeBSD 4.8-STABLE #2: Wed Apr 16 13:00:01 EST 2003 /space/home/staff 4817509 2995755 1436354 68% /home/staff /space/db/mysql 4817509 2995755 1436354 68% /db/mysql /space/db/pgsql 4817509 2995755 1436354 68% /db/pgsql /space/usr/cvs 4817509 2995755 1436354 68% /usr/cvs /space/usr/doc 4817509 2995755 1436354 68% /usr/doc /space/usr/ports 4817509 2995755 1436354 68% /usr/ports /space/usr/src 4817509 2995755 1436354 68% /usr/src /var/obj 1016303 747549 187450 80% /usr/obj /space/usr/local/office52 4817509 2995755 1436354 68% /usr/local/office52 I have built world many times and compiled ports without problem. I have an outstanding PR regarding nullfs http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/28566 I have now removed /usr/hack nullfs mount and retested startx. It all works fine now and I think this PR can now be closed (I'll submit PR followup after some more testing). Also at the time of this PR I stopped using nullfs mounts for /home because linux binaries would not work (no PR for this). I have also retested this and everything works fine. I think the warning in mount_null man page could be toned down. As noted in the '5.1-RELEASE TODO' emails nullfs is somewhat broken in -current. cheers -- tonym
