framework for adding/removing port-specific user

[Mikhail Teterin]

Hello!

Is there any framework in development to add port- and package-specific 
users/groups to the system?

I think, I need a special user for a new port I'm working on, and don't want 
to reinvent the wheel...

If not, any takers? So that a port can just declare

	CUSTOM_USER=	user:group

(or any part thereof) and have the neccessary spells cast for it?
