        be able to specify different paths for config files.

        <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>

    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.<span class=""><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>
    <br></div></blockquote><div>If we can consolidate that and use a single tool from the master neutron repository, that would be my vote. <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div bgcolor="#FFFFFF" text="#000000">

        <div>Also, if you can kindly review the code here: <a href="https://review.openstack.org/#/c/146508/5/neutron_vpnaas/services/vpn/common/netns_wrapper.py" target="_blank">https://review.openstack.org/#/c/146508/5/neutron_vpnaas/services/vpn/common/netns_wrapper.py</a>,
          I'd really appreciate it, as I'm not versed in the Linux proc
          files at all.</div>
