Previously posted in 2015: v1: https://www.redhat.com/archives/libguestfs/2015-June/msg00048.html v2: https://www.redhat.com/archives/libguestfs/2015-June/msg00118.html This series was posted about 4 weeks ago: v3: https://www.redhat.com/archives/libguestfs/2017-June/msg00287.html There is no change in this series except I rebased it against current upstream head and retested. Last time there was some discussion and patch review, but no change appears to be needed. Rich.
