Subject: [PATCH 5/7] builddeb: Enable rootless builds
Date: Mon, 21 Sep 2020 00:25:54 +0200	[thread overview]
Message-ID: <20200920222556.10002-6-guillem@hadrons.org> (raw)
In-Reply-To: <20200920222556.10002-1-guillem@hadrons.org>

This makes it possible to build the Debian packages without requiring
(pseudo-)root privileges, when the build drivers support this mode
of operation.

See-Also: /usr/share/doc/dpkg/rootless-builds.txt.gz
