Title:
  Avoid tmpfs /tmp during ubuntu-image builds

Status in livecd-rootfs package in Ubuntu:
  Fix Released

Bug description:
  At present, the Ubuntu Desktop for Raspberry Pi images are failing to
  build [1] [2] with an apparent out of space issue. Although this
  appears to occur *after* the rootfs has been allocated, it appears the
  file-system image is sparse and thus doesn't take much space until it
  is actually populated.

  ubuntu-image (which is the tool used to build these images) defaults
  to using /tmp as its working directory. This is now a tmpfs mount on
  plucky, and thus of extremely limited space (at least compared to the
  persistent storage). We should specify --workdir to avoid /tmp.
