initramfs-init: autodetect serial uses commandline
Starting with the changes merged in !126 (merged) all available tty* devices will become login shells. This collides heavily with the use of alpine on embededd platforms - oftentimes, those are used for serial peripherals.
This has been mentioned in
and
this commit tries to find a middle ground, by adding the command line option "autodetect_serial". Qemu users will easily be able to add this, while it is not something you will accidently put into your embedded command line.
