At the moment I'm building my imageswith image builder. With it I add some of my own software through FILES= and some additional packages through PACKAGE="tcpdump ..."
Once I verified and tested the build to be functional for me I would like to freeze the state of the official .ipk packages and keep using these package releases until I decide it's time to upgrade to newer verisions.
I was thinking about using the ./dl/ folder (contains all upstream packages needed for the build) as only source for further builds and thus keeping the packages at a stable version. Unfortunately I can't find a way to make this work.
any hints warmly welcome!
