Very very bad. Well, I would check the CVS logs to see why it had been done, if it came like that from 4.4BSD then we should change it, but otherwise consider why it was added. > This also rises some questions about 'nfsd -r'.

Kill nfsd and > restart does the same, and the binding is done the right way. I'd like to kill 'nfsd -r' however it makes more sense to fix -r so that it works with -h than to just remove the functionality. -- -Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
