We have a lot of shared projects and the group membership limit in NFS bites us pretty badly, so we use ACLs to work around it. There are other things in NFSv4 we need too, but ACLs are a biggie. I think I'm going to look at OpenIndiana next. It should give similar performance to what we're seeing with OpenSolaris, but unlike OpenSolaris it's still maintained. A major reason I was hoping to go with FreeBSD instead (other than familiarity) is better hardware support, though. Finding disk controllers that work with Solaris is a real headache. -- David Brodbeck System Administrator, Linguistics University of Washington
