This is not as simple. ttyS1 is the the console name and ttysclp0 is the tty name. This has mostly historic reasons and it obviously causes problems. But there is documentation out that that actually describes the use of console=ttyS1 console=ttyS0. to have console output on both sclp consoles and there are probably scripts using ttyS1.
I am wondering. The tty for ttyS0 is named sclp_line0. Does this work in LPAR?
I ran into this problem with qemu-system-s390x, so not sure about LPAR. Would changing the tty name also cause problems?
My point was more that a similar issue should happen when installing in LPAR. LPAR uses the line mode style console which is ttyS0 for the console but sclp_line0 for the tty. How does the debian installer handle this?
Regarding your patch I fear that this patch would break existing setups so we cannot use it as is.
