File 0009-pid1-handle-console-specificities-weirdness-for-s390.patch of Package systemd
From 09184a555aec3ef612425ba6fe596cf05383ca09 Mon Sep 17 00:00:00 2001 From: Franck Bui <fbui@suse.com> Date: Fri, 10 Jun 2016 15:19:57 +0200 Subject: [PATCH 1/1] pid1: handle console specificities/weirdness for s390 arch The 3270 console on S/390 can do color but not the 3215 console. Partial forward port of 0001-On_s390_con3270_disable_ANSI_colour_esc.patch from SLE12-SP1. A bunch of the previous code has been dropped since some changes imported from upsteam made them uneeded. The remaining bits are probably hackish but at least they are now minimal. It was an attempt to address bnc#860937 to automatically turn the console color mode off by passing $TERM=dumb when the specified terminal device is other than "3270". For more details, see https://www.ibm.com/docs/en/linux-on-systems?topic=setup-kernel-parameters. See also a short discussion which happened on @systemd-maintainers whose $subject is "[PATCH] support conmode setting on command line". [fbui: fixes bsc#860937] Don't warn if "conmode=" is missing as this option should not be passed on s390x KVM.
