• if available: execute
• automatically empties the folder /var/local/ setup after successful execution of the install script
• If the install script ends with exit-code 100, the system restarts and the script is called again
• installation
• is in /usr/etc
• must be executable (chmod +x)
• template is in webic-setup (siehe auch haprotec-setup)
• is executed by systemd on every boot
• service file is in /etc/systemd/system
• template is in webic-setup.service (siehe auch haprotec-setup.service)
• activate with sudo systemctl enable webic-setup
