Linux One-Liner Config Backup

So here at $newjob we've ran into Linux server, in all three environments, with huge uptimes and little documentation.  My co-workers already had one such beast get a forced reboot and things did not work correctly when it came back up.
So this morning I lucked into a nice one-liner that will pull all the infos.  Seriously it's damn good.  Props go out to /u/WOLF3D_exe
