I have tested this with Ubuntu packages, setting the build ID to e.g. "build3". Your suggestion of prefixing the build ID with a number (i.e. 1build3) doesn't seem necessary if we ensure that this change becomes effective only in a new version of firefox, because the build ID won't matter in the version comparison, e.g. from 68.0_20190701120911/20190701120911 to 68.0.1_build1/build1.
Dave, I have submitted https:/ /phabricator. services. mozilla. com/D37722 for review, I hope you and other build config experts can comment.

Or am I missing a use case?
