# Note that this recipe explicitly creates a serial-getty@ service for every tty
# in SERIAL_CONSOLES. This is typically not always needed with systemd as it
# will probe at boot and generate getty instances for any active consoles as
# required.  This recipe (enabled via disabling serial-getty-generator in systemd)
# should only be used if the generator is not appropriate.

# As this package is tied to systemd, only build it when we're also building systemd.
