The first version is the only correct one.
The "tty_io.c: process 1 (swapper) used obsolete /dev/cua0 - update software to use /dev/ttyS0"
is a non-harmful bug in uart.c. Just ignore it or change the first
occurence of TTYAUX_MAJOR to TTY_MAJOR.

They point to /dev/console, which is your boot-console.

/dev/stdin, /dev/stdout and /dev/stderr doesn't have anything to do
with anything.
