Gilles Lenaerts developed an optional Netifd integration toggle for ModemManager within the openwrt/packages repository, focusing on build system configuration and package management using Shell scripting. By enabling the ability to disable Netifd support, Gilles removed related dependencies and cleaned up unused components such as the netifd-proto.sh inclusion in modemmanager.common. This approach reduced the build surface and maintenance overhead, resulting in a smaller image size and improved configurability for targeted deployments. The work provided a more flexible integration path for ModemManager, supporting easier future enhancements and simplifying maintenance for OpenWrt package deployments without introducing new bugs.
