- Refactor dnsmasq configuration and scripts for improved variable handling and clarity - Updated dnsmasq configuration files to use direct variable references instead of data source functions for better readability. - Modified setup scripts to ensure they are run from the correct environment and directory, checking for the WC_HOME variable. - Changed paths in README and scripts to reflect the new directory structure. - Enhanced error handling in setup scripts to provide clearer guidance on required configurations. - Adjusted kernel and initramfs URLs in boot.ipxe to use the updated variable references.
