VGA installer image defaults to serial console, serial console is default in GUI settings
When booting from a VGA installer such as the ISO or VGA USB memstick, the boot menu is set to Serial.
See attached image.
It does keep using VGA when it boots and the installer works OK, so it's possible that it's cosmetic but it's still confusing.
Additionally, when going to System > Advanced, Admin Access tab after a clean install, the default console selected there is serial despite there being no preferred console in the configuration. If the user presses save without correcting that, they could lose access to the console afterward. This may not be related to the installer problem, and could move to its own Redmine issue if needed. That option may need to default to a neutral/empty value of "Default" so it doesn't change without user intervention.
