okay, then let's see if this is a useful purpose for dbus.

Hypothetical:

Let's say I need a root-running daemon that can actually make chroots
and submit items into chroots to be built. Would it be reasonable and
safe to use dbus to send these requests to the daemon? Is there any way
of restricting or validating WHO sent it?
