There should be progress on this particular point soon when I get oe-replicate-build prototype to function. It also records the list of needed sstate objects into the replica bundle (in the form of locked-sigs.inc, which is in itself not included into the build conf), and if you place that bundle next to sstate, and make a superset of all the objects in all bundles registered that way, you have a list of things that can be pruned from the cache without loss of build times. There could also be more interesting use cases, like querying the sstate server for available builds with guaranteed sstate coverage etc. Alex
