From 673abd92f999829bdd67d0273c43570a62123a63 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Fri, 18 Feb 2011 15:32:57 +0000 Subject: conf/machine: Drop older machines with no recent updates These are all moving to meta-extras. Ideally in the future machines such as these will be maintained to topic specific layers as we move to a more layer oriented model. If this causes a problem for anyone please discuss it on the mailing list.
