  | On NetBSD-8 "mount -f -r -u /" should just work.

If by "work" you mean preventing anyone from changing a password, preventing
resolv.conf from being updated by dhcpcd (or whatever) not allowing dumpdates
to be updated, ...

I'm with Manuel, why would anyone want to do that?     A read-only /usr makes
sense, read only root really doesn't (regardless of how nice it might seem).

ps: Dan, in the past, NetBSD didn't really (and at times, explicitly) support 
remount to readonly of anything, not only root.   On anythimg older than -8
attempting it (if on a version where the kernel permits it) can be dangerous
if you're not really careful about what you're doing (more so for root than
anything else).
