Subject: [Buildroot] [1/1] fs/cpio: sort 'find' utility output (reproducible builds)
Date: Mon, 29 Jun 2020 15:37:01 +0300 [thread overview]
Message-ID: <20200629153701.7c2c5ca4@monakov-y.xu> (raw)
Order of find utility results are not sorted and depend on items
attributes, so cpio produces different results across machines.
This patch sorts find output before piping to cpio to make
builds reproducible.
