In reading the below thread, I get the impression that there might be a slight problem with the v.10 of refractasnapshot (beta version).
Refracta 10 (almost)My probIem and the above problem may be one in the same. I don't know for sure as the above discussion is over my head, mostly. I have a situation that upon booting, the user will already be logged in, and entering the command "exit" will not log them out. I am using v.10 (not beta) of refractasnapshot and v. 9.1.9 of refractainstaller. I don't know which one is the culprit so I will mention both. This happens not on the livedvd but rather on the installed os.
I just tested this by installing the lesser versions of these programs, 9.3.4 snapshot and 9.1.8 installer, and these two function perfectly in that upon booting the user will not be logged in. At this point either a user or root can login.
I think something has been changed in the newer version(s). Just wanted to report what I found.
