- Updated `evofw-firewall.sh` to correctly handle exit codes from the `curl_policy` function, ensuring proper script termination based on policy retrieval status. - Enhanced `install.sh` to always use single quotes for configuration values, improving safety for names with spaces, and refined the logic for updating the `KERNEL_BACKEND` in the configuration file. - Updated documentation to reflect the changes in quoting and exit behavior during installation and synchronization processes.
