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 smartmontools curl
### Start reHDD after boot without login (as a tty shell)
nano /lib/systemd/system/getty@.service
and replace the [Service] with this:
```
[Service]
WorkingDirectory=/root/reHDD
ExecStart=
ExecStart=-/root/reHDD/reHDD
StandardInput=tty
StandardOutput=tty
Restart=always
RestartSec=1
UtmpIdentifier=tty1
TTYPath=/dev/tty1
TTYReset=yes
TTYVHangup=yes
TTYVTDisallocate=yes
SendSIGHUP=yes
```
systemctl daemon-reload
nano /etc/systemd/system/reHDDSettings.service
```
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/bin/bash /root/reHDDSettings.sh
[Install]
WantedBy=multi-user.target
```
nano /root/reHDDSettings.sh
```
#!/bin/bash
dmesg -n 1 #disable overlay if a drive is attached/detached
# remove comment for the following to activate log telemetie
# curl -k -T /root/reHDD/reHDD.log -u "fgggfffgfgfgfg:" -H 'X-Requested-With: XMLHttpRequest' https://schuttercloud.com/public.php/webdav/`echo $(date '+%Y-%m-%d_%H-%M')`_reHDD.log
rm -f /root/reHDD/reHDD.log
```
chmod +x reHDDSettings.sh
Make sure the binary reHDD is in /root/reHDD/
Add your system drive in /root/reHDD/ignoreDrives.conf like:
```e102f49d-5ed5-462b-94c5-ef66a4345671```
Get your UUID via blkid /dev/sdX
