Work items:
[cjwatson] Log total time for livefs builds: DONE
[lamont] Switch to tmpfs for non-DVD builds: TODO
[lamont] rsync tree to a safe location following debootstrap, and following non-DVD builds; copy this back as the starting point when necessary, but only if the corresponding archive timestamp is correct: TODO
[lamont] Investigate effects on parallelisation of livefs builds: TODO
[lamont] Investigate removing /usr/share/doc report and fdupes run from release builds (not needed; timing reveals this takes under ten seconds): DROPPED
[cjwatson] Add and use dpkg option to turn off syncing entirely: DONE

There was previously a work item here about evaluating live-helper as a replacement for livecd-rootfs; this has been moved to https://blueprints.launchpad.net/ubuntu/+spec/foundations-o-live-build.
