-Instructions how to create a standalone machine that boots directly to reHDD. This is aimed for production use, like several drives a day shredding.
-* Start reHDD after boot without login (as a tty1 shell)
-* Start dmesg after boot without login (as a tty2 shell)
-* Start htop after boot without login (as a tty3 shell)
-* Upload reHDD log every 12h if wanted
