With this mechanism we reach very good reuse across rebuilds with basically just 2 packages changed (and these are expected): dl9pf@elrond:~/repobuild-local/build-x86-64-repro> bitbake agl-demo-platform-crosssdk Sstate summary: Wanted 17 Found 8 Missed 9 Current 4282 (47% match, 99% complete) --------------------------------------------------------------------^^^ !!
