# systemd needs getty.service for VTs and serial-getty.service for serial ttys
# note that console-getty.service should be used on /dev/console as it should not have dependencies
# also patch the file to use the correct baud-rate, the default baudrate is 115200 so look for that
# systemd provides multiple units to autospawn getty as neede
# * getty@.service to start a getty on normal TTY
# * sertial-getty@.service to start a getty on serial lines
# * console-getty.service for generic /dev/console
# * container-getty@.service for a getty on /dev/pts/*
#
# systemd defaults to only have getty@tty.service enabled
# * DefaultInstance=tty1 in getty@service
# * no DefaultInstance in serial-getty@.service
# * WantedBy=getty.target in console-getty.service
# * console-getty is not enabled because of 90-systemd.preset
# We want "systemctl preset-all" to do the right thing, even when run on the target after boot
# * remove the default instance of getty@.service via a drop-in in /usr/lib
# * set a new DefaultInstance for getty@.service instead, if needed
# * set a new DefaultInstance for serial-getty@.service, if needed
# * override the systemd-provided preset for console-getty.service if needed
# the generator systemd-getty-generator will
# * read the console= kernel command line parameter
# * enable one of the above units depending on what it finds
#
# Systemd defaults to enablinb getty@tty1.service
#
# What we want to do
# * Enable a getty on $BR2_TARGET_GENERIC_TTY_PATH
# * Set the baudrate for all units according to BR2_TARGET_GENERIC_GETTY_BAUDRATE
# * Always enable a getty on the console using systemd-getty-generator
# (backward compatibility with previous releases of buildroot)
#
# What we do
# * disable getty@tty1 (enabled by upstream systemd)
# * enable getty@xxx if $BR2_TARGET_GENERIC_TTY_PATH is a tty
# * enable serial-getty@xxx for other $BR2_TARGET_GENERIC_TTY_PATH
# * rewrite baudrates if a baudrate is provided
