## insertroleaccount accountname [uid] [gid]
##   This routine will create a role account on the system with the uid (and
##   optional gid) specified.  It will check to make sure that the id names
##   are not duplicated but relies on useradd and groupadd to emit errors if
##   the numeric ids would be non-unique.  Although they are optional, it is
##   recommended that the uid and gid fields be specified since Slackware
##   makes an assumption that role accounts will have ids below 100, and left
##   unspecified useradd will pick a uid above 1000.
