- Create /etc/opkg/customfeeds.conf with secubox feed pre-configured
- Install file via Makefile instead of postinst script
- Mark as conffile to preserve user modifications on upgrade
- Add .gitignore to exclude built .ipk files from git tracking
(packages are embedded at build time by embed_local_feed)
