I believe that you have a stale mount(8) binary compared to your rc.d
scripts.  Did you do a full 'make buildworld' and 'make installworld'
before doing mergemaster?  You can probably remove /etc/rc.d/mountlate
for now and use mergemaster -i to install it back later.

No idea here.  What changes have you made before this happens?
