The build-info package rebuilds every time, as it generates the /etc/build-info file with info about the build. You can skip this by using "build-pkgs --no-build-info". SM rebuilds because it has a dependency on build-info.

The packages mentioned are: sm-common-debuginfo-1.0.0-20.tis.x86_64.rpm sm-common-dev-1.0.0-20.tis.x86_64.rpm sm-common-libs-1.0.0-20.tis.x86_64.rpm sm-eru-1.0.0-20.tis.x86_64.rpm sm-common-1.0.0-20.tis.src.rpm sm-common-1.0.0-20.tis.x86_64.rpm build-info-1.0-4.tis.src.rpm build-info-1.0-4.tis.x86_64.rpm build-info-dev-1.0-4.tis.x86_64.rpm Is this behavior a bug? otherwise why are those packages built every time if they have the same version? Note: The fix for the bug is ready for review https://review.openstack.org/#/c/634513/ Regards Felipe Ruiz / Pipo / Tranzemc Before anything else, preparation is the key to success.
