    RFC: easy & straightforward lxc unprivileged container uid/gid remap strategy

    Seems very interesting but I cannot understand how to install pylibacl (the script correctly says that it's missing). I've tried to search for the correct package but I canno find it. Also tried to install on the host acl package but still pylibacl seems to not be provided by that. Any help?
