NetBSD does not currently support moving from read-write to read only,
you need to boot with the file system in read only mode (you can switch
to read-write later if you need to.)

I have a patch you can apply that will allow switching to read-only mode,
but you do need to be very careful - the ability to do that was removed
because it does not always work correctly, to switch to read-only mode takes
some care to make sure the filesystem is in a suitable state first (the
system should simply make it work, but no-one ever found out why it didn't.)
