        is adding support for StrongSwan VPN, which needs mount bind to
        be able to specify different paths for config files.
        <div><br>
        </div>
        <div>The code, which used some older patch, does a test for
          /proc/1/ns/net, instead of /proc/1/ns/mnt, because it stated
          that the latter is only supported in kernel 3.8+. That was a
          while ago, and I'm wondering if the condition is still true. 
          If we know that for Kilo and on, we'll be dealing with 3.8+
          kernels, we could use the more accurate test.</div>
        <div><br>
        </div>
        <div>Can we require 3.8+ kernel for this?</div>

    I think we can but it's better to check with distributions. Red Hat
    wise, we ship a kernel that is newer than 3.8.<br>

    Ideally, you would implement a sanity check for the feature you need
    from the kernel. Though it opens a question of whether we want to
    ship multiple sanity check tools for each of repos (neutron + 3 *aas
    repos).<br>
