[lxc-devel] [PATCH] Add support for Linux for SPARC distribution host and template
wim.coekaerts at oracle.com
wim.coekaerts at oracle.com
Tue Dec 22 22:25:00 UTC 2015
From: Wim Coekaerts <wim.coekaerts at oracle.com>
Linux for SPARC is a free community Linux distribution for SPARC hosted by Oracle. See : https://oss.oracle.com/projects/linux-sparc
While the distribution is based on Oracle Linux it does have some differences and since it's not actually Oracle Linux I decided to add a separate template rather than having the Oracle Linux template also support Linux for SPARC.
This patch adds the lxc-template for Linux for SPARC and it also adds Linux for SPARC in the configure.ac as a distribution target to build.
