* TODO items in code.
* If priority is critical, should skip tasksel and dselect runs, and force
  an install of standard. (?)
* allow choice of dselect or deity. The problem is (besides deity's requent
  segs in my testing), that deity probably doesn't know about dpkg
  --set-selections settings, so it pobably won't see what tasksel selects.
* tzsetup asks for a country. Then so does apt-setup. Should only ask once,
  if possible.
* if apt-setup fails an apt-get update run, should offer to retry as well
  as the two choices it gives now, since it might be intermittent network
  problems

Apt-setup:
* Add full support for selecting a non-us mirror to use. Current non-us
  support was added quickly and always uses the same mirror.
