Why can I not re-bind #M?
/sys/src/9/port/chan.c:1374
I want to use auth/newns to flush out my namespace
then build a new one including some bits of devcons.
Is this a security issue for cpu servers? I cannot see
what it is protecting me from.
Also, why is this done here and not in fsattach() of devcons
(with a refcount)?

#M is not a nameable device.
It is a pseudo-device representing mounted connections.
Instead of writing
bind -b #M123 /dev
You are supposed to write
mount -b /srv/whatever /dev
My memory is that the name space files use
the latter form unless the original name is gone.

#M, but devcons? devcons is #c

Perhaps, Steve wants rio-simulated /dev/cons.
Steve, doesn't mount -b $wsys /dev in the new ns do the trick?
