Nice.

I have taken the liberty to extend your script to handle gzipped
tarballs of a root filesystem using the argument -t. With the stuff I
have added I was able to use the script to install a lxc prepared
tarball of Debian stable with your install script;-)

I have simply added in the installed script so no diff (Sorry, bad move
but I got exited ;-)
