This code in hwconf.c
        if (x==0) {
                /* This is a sick and gross hack. */
                fd=open("/tmp/ranXconfig",O_CREAT|O_EXCL,0644);
                if (fd!=-1) close(fd);
        }

and the corrosponding test in /etc/rc.d/init.d

        # However, if they did configure X and want runlevel 5, let's
        # switch to it...
        if [ -f /tmp/ranXconfig ]; then
            grep -q "^id:5:initdefault:" /etc/inittab && telinit 5
        fi

Can allow a user to force a system into run-level 5, even if the sys-admin
selected level 3 at bootup.  (Assuming that run-level 5 is the default) 

This is done by a simple 'touch /tmp/ranXconfig', and will confuse the
inexpreinced admin no end.  (Tested on RH 7, looks like it will work on
6.2)

Wouldn't it be better to use an environemnt variable or the like to convay
this instruction?  (Or at least check that root put the file there in the
first place)
