I pushed an older version of hammer to Shaman for the purpose of bisecting, but Shaman refuses to build it with:

+ dch -v 0.94.8-8-g8c6ea16-1 autobuilder
dch: fatal error at line 1141:
New version specified (0.94.8-8-g8c6ea16-1) is less than
the current version number (0.94.9-1)!  Use -b to force.

See https://shaman.ceph.com/builds/ceph/wip-hammer-0-94-9/8c6ea16254bfc726b4090dc6ceb97a4fe69d3a0c/default/13908/

Note that the SHA1 8c6ea16 is contrived. It's really v0.94.9 but I had to do "git commit --amend --reset-author" on it to get Shaman to build it (since it appears to ignore branches older than a certain date). This caused the "git describe" output to change from v0.94.9 to v0.94.8.
