Handling of tty is a bit tricky, we need to aggressively disable what systemd does with tty1 then update for what buildroot wants to do Rework the whole tty generation to work with presets Signed-off-by: Jérémy Rosen <jeremy.rosen@smile.fr> --- package/systemd/80-buildroot.preset | 5 ++--- package/systemd/systemd.mk | 25 +++++++++++++++++-------- 2 files changed, 19 insertions(+), 11 deletions(-)
