I havent used it in years, either. I recall amd changing its own idea
of the mount-point without (necessarily) telling the kernel.  maybe
I'm misremembering. We can discuss it offline (after i get more

systat vmstat keeps printing lines about a namei proc-cache...
now you mention it maybe it never has nonzero hit rate.

nullfs doesnt blow up on mount anymore, but it may still be horribly
broken internally. i just wondered why it was absent.

the rest youve covered.  (well, you did ask for it:)
