Execute command set fish_color_host blue|red|yellow|magenta depending of the power regulation.

Hostname

No reboot required with systemd : sudo hostname new-hostname

Tweaks

Scripts are named <component>-<task> where <component> is the part to be tweaked and <task> the purpose of the script, which can be install to install software of this part and custom to configure them as Jovian does.

Installation must be made before customization.

Set up SSH

vim .ssh/authorizedkeys

Test if working.

sudoedit /etc/ssh/sshd_config

Auto-update

Scripts are in Server/Scripts/Update.

Edit the root crontab :

0 2 * * * /home/jovian/Cron/update_system > /home/jovian/Cron/logs/update_system_log.txt 2> /home/jovian/Cron/logs/update_system_error.txt
0 3 * * 4 /home/jovian/Cron/reboot_system > /home/jovian/Cron/logs/reboot_system_log.txt 2> /home/jovian/Cron/logs/reboot_system_error.txt
@reboot /home/jovian/Cron/boot_system >> /home/jovian/Cron/logs/reboot_system_log.txt 2>> /home/jovian/Cron/logs/reboot_system_error.txt

Note : it's a home-made solution. Prefer unattended-upgrades for real use cases.
