2015-03-23 ---------- Now ensuring that `apt-get dist-upgrade` occurs at least once before package manifest is computed. This is because distributions usually don't store old versions of packages in the repos, so we can't download the exact package version we have installed if it's out of date. gbuild now has a --upgrade flag that forces an upgrade after the first one. Other Notes =========== Important: We are planning on switching from using lxc-start to using lxc-execute. lxc-execute requires lxc-init (or init.lxc) to be available on the guest at one of the expected places. You might have to manually install lxc on your base VM image or recreate the image. To enable this now (required for Ubuntu 14.04), do: export LXC_EXECUTE=lxc-execute If your guest is more recent than the host, all bets are off, since lxc-execute may not be able to find the lxc init.
