Major Description
Right now there is no build numbering (beyond -1 ) for different packaging attempts and bigtop releases.
There is no workable way to increase build numbering in Bigtop. (At least this is the situation for ubuntu and debian, have not checked RPM).
This leads to indentical package versions and buildnumbers for different bigtop builds when no package version upgrade has been made. This is not desirable , since it essentially disables package upgrades at all.
There is a BIGTOP_BUILD_STAMP which could be used to introduce the needed semantics but sadly this BIGTOP_BUILD_STAMP is appended to the PKG_VERSION part of the numbering, not the RELEASE_VERSION part .
I vote to move BIGTOP_BUILD_STAMP to the "right" place in the package-version: Appending to RELEASE_VERSION
