Description of Problem: When something goes wrong during startup, sulogin is called and it displays: ... or type Ctrl-D for normal startup but when I hit Ctrl-D I get a reboot. I understand that reboot is the correct behavior, but would it be possible to alter the message in some future release ? It should definitely not be promising a "normal startup".
The problem is that while the message comes from sulogin, the fact that it reboots is because of the code that *calls* sulogin; sulogin itself doesn't know that it will reboot afterwards. So you'd be changing the message for cases where it would be relevant.
As you wrote, sulogin does not know what is coming next. It seems logical to me that in such situation it should not promise a normal startup. I would suggest a neutral message like: Give root password for maintenance (or type Control-D to continue): Anyway it is not a real bug, just a small annoyance, so simply close this bug if you prefer.
Changed in 2.84-6.
