title: Using user's dir to store copied python3 packages
body: <p>I'm defining an update procedure on the air-gapped standalone RedHat7 server with the preinstalled python3 and
  basic packages.</p>
  <p>The python3 applications are developed on a host with an Internet access, and are delivered to this standalone
  server using DOK.
  Additional packages can't be installed using pip, but must be trasfered from development host to the local user's home directory.</p>
  <p>I'm looking for a proper way to update and activate python3 applications on this standalone server, without appending a new package path using sys.path.append(&quot;/home/user/packages/pack_N&quot;) before importing it.</p>
  <p>Thanks</p>
