I've created the container using /usr/lib/lxc/templates/lxc-ubuntu,
as stated before. /etc/init/lxc.conf is created, holding
--- snip ----
# fake some events needed for correct startup other services
description "Container Upstart"
start on startup
script
rm -rf /var/run/*.pid
rm -rf /var/run/network/*
/sbin/initctl emit stopped JOB=udevtrigger --no-wait
/sbin/initctl emit started JOB=udev --no-wait
end script
--- snap ----
only one other script is in /etc/init of the container "hostname.conf":
--- snip ----
# hostname - set system hostname
#
# This task is run on startup to set the system
# hostname from /etc/hostname,
# falling back to "localhost" if that file is not
# readable or is empty and
# no hostname has yet been set.
description "set system hostname"
start on startup
task
exec hostname -b -F /etc/hostname
--- snap ----
Starting the container with "lxc-start -n con" just hangs. Looking
at the host from an other shell (or using "screen -dmS con lxc-start
-n con"):
--- snip ----
12232 ? Ss 0:00 SCREEN -dmS tps lxc-start -n tps
12234 pts/3 Ss+ 0:00 \_ lxc-start -n tps
12235 ? Ss 0:00 \_ /sbin/init
--- snap ----
That's it. Hangs running init! At least I would expect to have
something like seen after starting linux on real hardware.
