This fixes a couple of issues with podman top. podman top --latest USER HUSER Now shows you the User inside of the containers usernamespace as well as the user on the host. podman top --latest capeff capbnd Now has headings that differentiatiate between the Capabiltiies. We also have support for ambient capabilities. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com> Closes: #1286 Approved by: vrothberg
