From 0e72d71a67f8d29df926af2a8c249a521ee62680 Mon Sep 17 00:00:00 2001 From: Brad Bishop Date: Wed, 12 Aug 2020 07:03:47 -0400 Subject: meta-phosphor: systemd-policy: move to systemd Don't install systemd policy if: - systemd is not being installed - a non phosphor distro Use RRECOMMENDS for easy opt-out in Phosphor based distros.
