Are you talking about the www.netbsd.org diskless howto at
From the exports(5) BUGS:=20
"The export options are tied to the local mount points in the kernel and
must be non-contradictory for any exported subdirectory of the local
server mount point."
I.e., if you want to export the client /usr read-only, it has to be on
a different filesystem than the r/w client root. nullfs mounts come in
handy here, but seem to be an undocumented trick of the trade.=20
The howto gets that seriously wrong. Might be worth a PR.
