That is how I read the man page, too, long ago. But when I tried the -o option on the commandline, I was unable to send mount all of the mount_nfs commandline switches I needed. I either misunderstand the mount -o option, or it doesn't work for all of the mount_nfs stuff I tried to send it. In other words, the -o option seems to not like any of the many switches understood by mount_nfs .... hence I seemed to be forced to use mount_nfs directly. And that precludes using it in fstab. > What trouble did you have with fstab?

Since mount wasn't able to understand those switches on the commandline, I never tried anything in fstab, for the sake of not causing any problems with my boot. Anyone tried that sort of stuff in fstab? I'm a little skeptical. Thanks. BN
