More verbose TrueNAS install - error messages

Problem/Justification
There have been a lot of posts regarding hung TrueNAS installations without any real error messages to give clues as to what went wrong. Example post

Impact
Hoping to be able to see where the install is hanging up. Sometimes it just stops at a cursor. Current advice is to try changing BIOS options, removing hardware that may be causing it, etc. Sometime users try booting a live Linux version and that is fine.

User Story
The default install could continue as it currently is and the verbose option would just assist in troubleshooting these issues.

Not sure if there were options like this for the install so I didn’t vote. Awaiting feedback from members or developers familar with Linux / TrueNAS install.
