Hi lanas
I boot up normally in an xterm console and I have put an inittab which
includes
ttyS0::respawn:/sbin/getty -L ttyS0 9600 vt100
tty0::respawn:/sbin/mingetty --noclear tty0
and it also uses a serial console from the host once it bootup up. So after
bootup I know which /dev/pts is using as the xterm windown show which host
serial console it is attached. So I use SCREEN program to attach/deattach to
the UML, also you can capture with one session multiple consoles and
leave them running in the background and it works just fine. Sorry I can't
help you more.
