I can't do the same; if I put /var/spool/pcnfs into /etc/exports without exporting /var, all I get is: May 9 19:26:02 crydee mountd[1723]: could not remount /var/spool/pcnfs: Invalid argument May 9 19:26:02 crydee mountd[1723]: bad exports list line /var/spool/pcnfs -alldirs -network 195.208.220 -mask 255.255.255.0 and /var/spool/pcnfs is not listed in `showmount -e' output. > I ran Linux for 5 years prior to switching to FreeBSD.

So far I did not reach any stage of happiness yet... Config format is rather minor issue IMHO unless you have 100-line exports file which is unlikely. All in all, right now Linux NFS looks better for me: it has more features and is much faster. This might depend on many factors, of course. If your clients are Solaris or other commercial Unixes with NFSv3, FreeBSD might be a lot better for you than Linux. In my case, it is not. The bad part about Linux NFS was that pcnfsd tends to crash from time to time (esp. when printing files over 10MB), sometimes taking also lpd with him. --------------------------------------------------------------------------- Dr. Sergey Ayukov Sternberg Astronomical Institute http://www.ayukov.com Moscow, Russia http://crydee.sai.msu.ru/index-asv.html To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
