Reduced this to a regreassion in lxc-attach; it stopped reproducing the exit code of the executed command with 3.0.3: # dpkg-query --show lxc lxc 1:3.1.0+really3.0.3-8 # lxc-start -n test # lxc-attach -n test false; echo $? 1 # lxc-attach -n test true; echo $? 0 # lxc-ls -f with 3.0.4: # dpkg-query --show lxc lxc 1:3.1.0+really3.0.4-1 # lxc-start -n test # lxc-attach -n test false; echo $? 0 # lxc-attach -n test true; echo $? 0 I will now try to bisect this.
