I like this... it not only answers my user creation question but also
how/where to handle some of the setuid stuff. The only trouble is I'm not
sure how configure/make will like --with-mail-gid=mailman and
--with-cgi-gid=mailman if mailman doesn't exist until after the install.
I'll give it a go and see....

Cheers,

Sean

Maybe adding a user creation funcitonality to pkg_config and pkg_postrm
is a good solution. It isn't executed automatically and it removes the
burned from the user to execute the exact commands, since some packages
need to even do more things afterwards, like changing permissions and
ownership, or even create multiple users.

example from a private package:
INSTALLDIR="/opt/${PN}
MYGRP="mygrp"
MYUSR="myusr"
pkg_config() {
        einfo "Creating ${MYGRP} group if needed <=="
        if [ ! `grep -x "^${MYGRP}:.*" /etc/group` ] ; then
                groupadd ${MYGRP};
        fi

        einfo "Creating ${MYUSR} user by deleting a previous existing
entry if needed <=="
        if [ `grep -x "^${MYUSR}:.*" /etc/passwd` ] ; then
                if [ -d ${INSTALLDIR} ] ; then
                        userdel -r ${MYUSR};
                else
                        userdel ${MYUSR};
                fi
        fi
        useradd -m -d ${INSTALLDIR} -g ${MYGRP} ${MYUSR}

        echo "==> Updating permissions and ownerships <=="
        chgrp root `dirname ${INSTALLDIR}`
        chmod 755 `dirname ${INSTALLDIR}`
        chown -Rf ${MYUSR}.${MYGRP} ${D}${INSTALLDIR}
        chmod -Rf 775 ${D}${INSTALLDIR}

}

pkg_postrm() {

        einfo "Removing ${MYUSR} user if needed <=="
        if [ `grep -x "^${MYUSR}:.*" /etc/passwd` ] ; then
                if [ -d ${INSTALLDIR} ] ; then
                        userdel -r ${MYUSR};
                else
                        userdel ${MYUSR};
                fi
        fi

}
