From 4dc8dee0435bb63cbe474004b0a8df0363fe94dd Mon Sep 17 00:00:00 2001 From: Dan McGregor Date: Fri, 5 Sep 2014 06:28:58 -0600 Subject: [PATCH] Make root's home directory configurable. OpenEmbedded has a configurable home directory for root. Allow systemd to be built using its idea of what root's home directory should be.
