Subject: rootfs.mk: ensure all timestamp are set to SOURCE_DATE_EPOCH
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8cb13f4e6d5750957449b4c5740f64af11a9ad36;p=openwrt%2Fstaging%2Fzorun.git

rootfs.mk: ensure all timestamp are set to SOURCE_DATE_EPOCH

Some tools doesn't support SOURCE_DATE_EPOCH (e.g. initramfs images).
Ensure all files of a root filesystem are set to SOURCE_DATE_EPOCH.
Make initramfs builds reproducible (for ramips).
