Subject: build: Drop user/group ID/name from sysupgrade.tar
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1afe3d8443aacbaf72a9148448bc6e0e2d2d0a9c;p=openwrt%2Fstaging%2F981213.git

build: Drop user/group ID/name from sysupgrade.tar

Tar will automatically record the user/group ID and name for
files/directories. This reduces the reproducibility of the sysupgrade.tar
because most of the people don't use the same username as the OpenWrt
buildserver.
