neat
you made me think about creating a little helper around debootstrap so
you could have something like

env:
   NEURODEBIAN_DISTRO = sid
   NEURODEBIAN_DISTRO = sid-i386
   NEURODEBIAN_DISTRO = precise
   NEURODEBIAN_DISTRO = saucy

before_install:
   sudo nddebootstrap $NEURODEBIAN_DISTRO

and where/when needed to have things executed in that environment

 schroot -c $NEURODEBIAN_DISTRO ...

thus allowing to sweep through different Debian and Ubuntu releases on
travis... I wonder if its gods wouldn't get upset with a bit increased
bandwidth/cpu consumption ;)
