[4.0.4]: lxc-copy does nothing

lxc 4.0.4

After create first container:

# lxc-ls -f
NAME   STATE   AUTOSTART GROUPS IPV4       IPV6 UNPRIVILEGED
fedora RUNNING 0         -      10.0.3.104 -    false

(which has been created on btrfs) I’ve been trying to clone/copy it
So I’ve executed:
# lxc-copy -n fedora -N fedora-test -s -B btrfs
But that command does nothing and even does not print any warnings or errors … completly nothing (!! ?)
Man page is really enigmatic and using it is really hard figure oit what needs to be done. Am I doing that wrong way?
All what I want is just create clone of the existing zone with btrfs clone underneath.

On using strace I see only:

# strace -f lxc-copy -n fedora -N fedora-test -s -B btrfs
