Actually you do.  I have used this trick MANY times to fix messed up
/etc/fstab's and pre-devfs missing nodes in /dev.  The ability to do
this double mounting has been a big help.

No, they are concentrating on the part they see and use every day.
With the number of changes from FreeBSD 4.x -> 5.0; I could more easily
upgrade a machine to NetBSD at this point.  That is one of the problems
-- you're making yet one more user interface and sysadmin change when
there are already 100's.  Each one added still adds pain for users and
SA's.
