Subject: [PATCH 09/11] 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. And yes turning the console
|
|
color mode off by passing $TERM=dumb via the kernel command line would
|
|
have been much more easier and enough.
|
|
|
|
This is actually implemented by recent systemd. There's also another
|
|
command line option: systemd.log_color=off.
|
|
|
|
See also a short discussion which happened on @systemd-maintainers
|
|
whose $subject is "[PATCH] support conmode setting on command line".
