From 41b77edaceeabb5907eda95ff64ee8ec81551fe5 Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Mon, 21 Dec 2020 10:23:51 +0100 Subject: build: create tarball without self-referential hard links The current method of creating the tarball, which is to the hard-link the source directory to the target directory, results in self-referential hardlinks which can be observed using tar xf. This patch resolves this by using an intermediate tarball, held in memory, which collects files to be distributed. This is then unpacked in the target directory which is finally packed into the distribution tarball, a file.
