Comment 8 for bug 412825

As ubiquity does this dance around permissions so that the UI isn't ran as root, but things executed by it are, it was a bit confusing as to whether it was actually executing reboot as root. Somehow it appears to not have been, which begs the question as to why this was working for OEM Config, or for ubiquity-only mode in the first place. It doesn't seem like it should have been.

Nonetheless, a fix should be committed now.
