Split off between a privileged daemon and an unprivileged frontend

[ghost]

I'm proposing an idea for a new version of the hashbangctl program.
Multiple clients, one server.
Clients write to server, server interfaces with the system as root. Clients won't need sudo permissions.

Thoughts?
( lrvick also suggested to make hashbangctl upgrade it's runtime user level to root, thoughts on this too? )

So, lrvick did raise some good points. A server would be a lot harder to manage at the moment than to just get the client running. I'll get to working on a "no-calling-sudo" mode later.

I'm currently poking at something like that.
A draft of the protocol between frontend & daemon is documented, and I will push my branch to GitHub once it is sufficiently far along.

Huge success!

Finally figured out how to get gevent, provisor and Unix SOCK_SEQPACKETS sockets to play along. Also worked out how to do the getsockopt(SO_PEERCRED) call to ask the kernel about the identity of the process at the other end of the pipe.
