CONFIG_SERIAL_8250_RUNTIME_UARTS is currently set to 32 which leads to 32 /dev/ttyS*. The upstream default is 4. Is there a need to pre-create that many nodes? I noticed that it clutters the `systemd-analyze blame` quite a bit when looking for boot times. Maybe reduce it back to 4? Users that really need that many ports can set 8250.nr_uarts=32 on the kernel command line as documented upstream: https://github.com/torvalds/linux/blob/master/drivers/tty/serial/8250/Kconfig
