From 1b72d21bc3713b6c82f56e31e84413e0956fa4ed Mon Sep 17 00:00:00 2001 From: Samuel Mendoza-Jonas Date: Tue, 19 Jun 2018 16:51:50 +1000 Subject: [PATCH] discover/platform-powerpc: Read and write password hash from NVRAM If petitboot,password exists set it as the root password. This will be the password used to authenticate clients. This is the *hash* of a password as it would appear in /etc/shadow, not the password itself.
