This change uses the reexec package to run the update of the ldcache in a container in a process with isolated namespaces. Since the hook is invoked as a createContainer hook, these namespaces are cloned from the container's namespaces. In the reexec handler, we further isolate the proc filesystem, mount the host ldconfig to a tmpfs, and pivot into the containers root. Signed-off-by: Evan Lezar <elezar@nvidia.com>
