been using monolithic for a while, and just sat down
and got the whole binary build up and running
(still a bit hazzy with the user/login).

but in regards to what(hopefully I'm seeing this)your saying
is if loading a monolithic have semanage have the ability to
example: /usr/sbin/semanage -DB to a monolithic and/or adjust user/login.
just like binary without the need for the source.
(well need for the source to do the initial install)

if so.. that would be nice, i.g. with the suse thing
they have monolithic(if above was possible)I would not have had to
download any source to add login/user etc... just make the changes there 
on the spot like binary.
