Document qusal.ConnectTCP in dev's Access Control as it defaults to deny
and causes confusion to users why it doesn't work by default. This is
an exception of the rule that a formula cannot document the RPC service
of another formula to avoid duplication.
Ideally, it would be a Qrexec socket service, but it doesn't handle DNS,
only accepting IPs. The dev qube is now non-networked and network,
especially to remote git repositories can be acquired via the proxy that
is going to be installed in every netvm.
- Default sys-net and sys-firewall to disposable;
- Set global and per vm preferences by starting the qubes or shutting
down them when necessary; and
- Less manual steps remaining for the user: just rename the net qube, as
it can only be done via Qubes Manager.
