Description Adam Williamson 2021-03-11 03:09:27 UTC 
In Fedora 34 beta candidate 1, the systemd debug-shell does not work. If you enable debug-shell.service and boot, on tty9 you don't get a root shell as you should, just a flashing cursor. In the journal you get this:

Oops.
Comment 2 Zbigniew Jędrzejewski-Szmek 2021-03-11 19:05:26 UTC 
Isn't this the same as #1933902?
Comment 3 Adam Williamson 2021-03-11 19:17:44 UTC 
oh, probably yes. I think I forgot about that one. Sorry!
