Issue
The installer profile boots up to the boot menu and when it "automatically boots" it moves to a blank unresponsive terminal. It does seem to respond to SSH but there's no way to authenticate when connecting via SSH.
Suggested Fix
I'm not sure if there's a profile issue or if the new minimal ISO have an issue with the LISH/GLISH bits. I'm not educated enough to give a good suggestion to fix it.
I'm debating customizing an installer ISO to insert my public keys as trusted for root.
Then just using my custom ISO I flash to the installer "disk"
