Thank you for your quick answer, Serge.

Actually, my laptop is running 0.9.0-alpha3 and when running lxc-checkconfig 
I have a red output :
Cgroup namespace: required

While on a Debian stable server at work (0.8.0) I have a green :
Cgroup clone_children flag: enabled

I don't know why those differences show up.

1.0.0 should transition to Debian testing in a week or so and I will wait 
until then (albeit I did not see relevant bug reports or entries in the 
Debian changelog).

Thanks again,
