Subject: fs/common.mk: do not store original names and timestamps when creating gzipped rootfs
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=44d17dd128164cfe7870f5bef279e273ba59f83d;p=buildroot.git

fs/common.mk: do not store original names and timestamps when creating gzipped rootfs

Using the GZIP environment variable to pass gzip options is
deprecated, and therefore we are going to remove the "GZIP = -n"
definition from the main Buildroot Makefile. In preparation for this,
we explicitly add the -n argument to the gzip call in fs/common.mk to
ensure reproducibility.
