Code Issues Proposed changes

Store journal in export format not native 

We do this because not all distros/release have the tool to properly
export the journal data in native format (specifically
systemd-journal-remote). We can however trivially store it in the export
format then anyone that wants to review these logs can import them to
native format locally using systemd-journal-remote.
