  30 Make basefile with desktop packages preinstalled
  31
  32 The longest amount of time when doing a new install is installing
  33 packages. We can make that faster by preinstalling them in a
  34 basefile. When a basefile is created, debootstrap allows you to
  35 specify extra packages, but in trisquel, most packages don't install
  36 that way. Not sure exactly why. So, we can do a fai dirinstall (fancy
  37 chroot) to install packages, then turn that into a new basefile.

  39 The script depnds on being in a directory with other scripts from it's repo.
