Bug#123661: boot-floppies: 3.0.18(cvs) serial console unusable on i18n enabled flavours (i386)
some additional information:
it is caused by the spawning of bterm in the /sbin/udbootstrap script.
i changed the script to:
if (</dev/fb0) 2>/dev/null && ! /usr/bin/tty | grep -q ttyS ; then
exec /usr/bin/bterm -f /unifont-reduced.bgf /sbin/dbootstrap
based upon the model in /etc/init.d/check_fb.sh. it worked in a chroot,
but failed when booted.
when i commented out the entire if .. fi clause, it worked fine.
