Subject: [gentoo-catalyst] [PATCH 07/12] catalyst: Factor out run_sequence()
Date: Thu, 29 Oct 2020 12:16:27 -0400	[thread overview]
Message-ID: <20201029161632.146732-7-mattst88@gentoo.org> (raw)
In-Reply-To: <20201029161632.146732-1-mattst88@gentoo.org>

This is preparation for the next patch, which will run the build
sequence in a separate mount namespace.
