In prefix, emerge not necessarily runs as 'root', thus has no permission
to create new users directly.

Years ago, I had exactly such an implementation for initialdays-prefix,
which unfortunately did not make its way into nowadays-prefix:
http://archives.gentoo.org/gentoo-osx/msg_02360.xml

It will need some love, at least for
*) ${ROOT} -> ${EROOT}
*) ${AFFIX} -> "usr/"
*) ${USERLAND} -> ${CHOST}
*) more platforms (not just Darwin, BSD, Linux)
*) test it

Just want to define this as one possible solution, not the _right_ one,
more ideas welcome.
