(ie. Not on an update/upgrade unless it has never existed before.) If this file is lost during a crash, the technically correct thing is to recover it from backups and not let the server start until it is recovered, since the information in it is critical to a correct reboot recovery of the NFSv4 state. So the answer is "no" for /etc/rc.d/nfsserver unless you don't care about correct server crash recovery. I don't know if installworld can differentiate between a fresh install and an upgrade? (I suppose it could create it if it doesn't already exist.) As such, I just documented it in "man nfsv4" for now, rick
