Hi,
Given that Yuriy says explicitly 'unix socket', I dont think he means
'MQ' when he says 'RPC'. I think he just means a daemon listening on a
unix socket for execution requests. This seems like a reasonably
sensible idea to me.
Cheers,

I thought of this option, but didn't consider it, as It's somehow
risky to expose an RPC end executing priviledged (even filtered) commands.
If I'm not wrong, once you have credentials for messaging, you can
send messages to any end, even filtered, I somehow see this as a higher
risk option.
And btw, if we add RPC in the middle, it's possible that all those
system call delays increase, or don't decrease all it'll be desirable.

Another option would be to allow rootwrap to run in daemon mode and
provide RPC interface. This way Neutron can spawn rootwrap (with its
CPython startup overhead) once and send new commands to be run later
over UNIX socket.
This way we won't need learn new language (C/C++), adopt new toolchain
(RPython, Cython, whatever else) and still get secure way to run
commands with root priviledges.
