Subject: [gentoo-catalyst] [PATCH 2/2] catalyst: create namespaces for building
Date: Tue, 6 Oct 2015 16:32:53 -0400 [thread overview]
Message-ID: <1444163573-11337-2-git-send-email-vapier@gentoo.org> (raw)
In-Reply-To: <1444163573-11337-1-git-send-email-vapier@gentoo.org>
This helps isolate the catalyst builds from the rest of the system
and allows us to build as non-root user in more cases. This might
not work everywhere, but it's a start (snapshot generation works).
