init

Documentation

Overview

Package init implements early userspace logic in go, replacing the functionality of initramfs's /init. It does the normal things such as decoding

real_root=UUID=nnnnnn

but also checks that the unit can/should boot in normal mode. It will display a menu on the attached LCD. This menu allows the user to initiate factory restore to the latest image, to a particular image, etc.

Impacted by build tags mfg, release, erase_integ.
