* Use consistent mtime timestampsGatis Paeglis2016-03-161-0/+27
This patch adds consistent_timestamps.bbclass which is a hackish way of resembling reproducible build - byte-for-byte identical binary packages from a given source. Naturally this is not a complete solution, but it fixes the issue described below. Real solution for this should be done by the Yocto project itself. In OSTree each new update is checked out with all files and directories having mtime=0, this breaks fontconfig cache validity check (mtime embedded in the cache should match the containing directories mtime). Yocto generates this cache file in poky/meta/lib/oe/rootfs.py::create by calling self._run_intercepts() after all packages have been installed. These timestamps are nondeterministic as they depend on current system time. By using ROOTFS_POSTINSTALL_COMMAND hook we can ensure that these embedded time stamps have a known time, which is a basic property of reproducible build system.
