I checked that and it shows exactly that. I'm accessing the container on its lxc-start console, so I'm not using SSH. Nevertheless, I recreated the container and it's no longer happening, so most probably I messed things up while struggling with locale autoconfiguration via preseeding and I was simply too tired to notice. :) Sorry for the noise, and thanks for the hints! -- Ivan Vilata i Balaguer -- https://elvil.net/ ------------------------------------------------------------------------------ Symantec Endpoint Protection 12 positioned as A LEADER in The Forrester Wave(TM): Endpoint Security, Q1 2013 and "remains a good choice" in the endpoint security space.
