# uname -a

# mount | grep /home
/dev/ad0s1e on /home (ufs, NFS exported, local, soft-updates)
# mount -u -o noexec /home
mount: /dev/ad0s1e: No buffer space available

# remove /home from exports(5)

# mount | grep /home
/dev/ad0s1e on /home (ufs, local, soft-updates)
# mount -u -o noexec /home
mount: /dev/ad0s1e: No such file or directory

That works on RELENG_4,5,6.

I'm sure these breakages never end until we get a comprehensive
regression test suit for mount code.
