I cannot login in after a fresh install, don't know root password, and it never asked me to create a user

> That's not similar, it's totally different. :-)
No. It's similar, because it was, in both cases, when adding users the 
installer did something unexpected. I think.

> Again, the installer's syslog would be useful.
Well, since the entire installation crached, I had to install again and thus 
the log got lost. Sorry.
