Crikey, Leszek,

that's an awesome amount of work. If you and julien agree on it, then I

Thanks,

Phill.

Unfortunetly the Installation fails after installing the base system, because it tries to install a package called lubuntu-desktop^ in the tasksel process which it cant find. I tried this with the modified tasksel version of yours. I even checked the modification you made but cant find the error.
