Dear Maintainer,

After building a testbed by
autopkgtest-build-qemu ceres /var/tmp/ceres-amd64.img http://deb.devuan.org/merged
and adjust /etc/inittab in the testbed so that it accepts login
from /dev/ttyS[01],

autopkgtest -U -B thunderbird -o /var/tmp/autopkgtest-thunderbird1  -- qemu --ram-size=2048 /var/tmp/ceres-amd64.img
