Instructions how to create a standalone machine that boots directly to reHDD. This is aimed for production use, like several drives a day shredding.

### Software requirements

* apt-get install hwinfo
* wget http://ftp.de.debian.org/debian/pool/main/s/smartmontools/smartmontools_7.1-1_amd64.deb
* dpkg --install smartmontools_7.1-1_amd64.deb 

### Start reHDD after boot without login (as a tty shell)

nano /etc/systemd/system/reHDD.service
```

Make sure the binary reHDD is in /root/reHDD/
Add your system drive in /root/reHDD/ignoreDrives.conf like:
``` /dev/sdX:e102f49d-5ed5-462b-94c5-ef66a4345671```
Get your UUID via blkid /dev/sdX

systemctl enable reHDD.service

systemctl enable reHDDSettings.service
