## Create Standalone with Debian 11
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
### Software requirements
* `apt-get install hwinfo smartmontools curl htop sudo`
* `zypper install hwinfo smartmontools curl htop sudo`
### Installation
