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.

I don't know. 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.
