The effective-set walk already resolves sub-manifests and delta chains in canonical order, so this is that walk with an archive writer. Members carry the F card's permission, so an executable stays executable. Two runs of one version are byte-identical: history supplies the order and the timestamps, and no uid, gid, or build host is recorded. A file the store does not hold is refused by name -- a partial archive looks exactly like success. check-in: 580d0691c7 user: dmestas tags: trunk
