The disk space (and time needed) for DWARF has been a problem for us especially as a source-based distribution because we can't assume all builds are done on some beefy centralised builder ;) I'll wait to give it a go until there's some pahole wiring, then I'll try daily driving it. Have you got a list of what's left to do and also what you need from the community? Or is this a preview of what you're working on and not expecting much discussion yet? cheers, sam
