The section about 'graphical login' suggests adding XSESSION variable to /etc/rc.conf (see last sentence of the section). According to bug 294449 comment #4 that is wrong. The section needs to be corrected.
Sorry, wrong bug number. Correct one is bug 294999 comment #4.
Hmm, sure enough. When I fixed the rest of our docs to use the env.d location, this one somehow slipped my mind. I'll take care of it.
Thanks for reporting; fixed in CVS.
