Steps to reproduce the issue:
I would like to test using a custom seccomp profile

docker run --rm -it --security-opt seccomp=default.json hello-world

The default.json file is the same here: https://github.com/docker/docker/blob/master/profiles/seccomp/default.json

Results

docker run --rm -it --security-opt seccomp=default.json hello-world

docker: Error response from daemon: linux seccomp: seccomp profiles are not supported on this daemon, you cannot specify a custom seccomp profile.

Should I add --security-opt seccomp=default.json to /etc/default/docker ?

Seccomp is not currently supported on Ubuntu 14.04, because the shipped libseccomp library is too old, sorry.

There is another issue here #22870 - I am going to close this one as it is outside our control. I want to do something about it if possible, but it is quite difficult unless the fixes are backported by Ubuntu.
