Arf. I don't know how to tackle this. I have been largely trying to get some record of the boot logs. I am unable to do so. As those are blank, and this other file, well, doesn't have the pertinent information.
Live-config, and console system startup logging fails.
I am not using autologin, and this is just stock debian jessie, about the only special things i pulled were installing yad, refracta installer and snapshot tool, and also changing sources.conf over to testing (i am to stick at permanently staying in testing; for now that is jessie). I do not consider switching jessie over to systemd as something special since systemd is going to be the default system daemon. I have always used the dd command for making a live-usb, this i do not think is the problem since i have never had a problem with dd before. I don't know what's going on, in fact i find it quite unexplainable. Why won't it at least load the login screen?
For the hell of it, i'll try burning to a dvd to see what happens.
EDIT: I got a little more in depth with the var/log/live directory.

:ERROR
username=guest should work

EDIT: yes that worked, that is extremely awkward though. On sysvinit, it would dump you to the login screen. This is completely strange how things are now (wtf?).
I did find another failure, but don't really see how it pertains to anything other than sudoers which i did configure specially for "passwd_time=0". whatever.
