Description Ed Maste freebsd_committer freebsd_triage 2016-02-11 15:30:01 UTC 
To support reproducible builds of FreeBSD we need to be able to produce byte-identical output from identical input for all files produced by the build.

makefs needs an option to control the timestamps emitted in its output, either by allowing the user to set an explicit timestamp or allowing timestamps to be set to the epoch or similar.
