well, mkdir can create it too :) but ok, those checks are so embedded
that i can ignore if the reportbug check if fooled to thing theres
another systems (there will be bigger problems indeed) so I will just
mimik their logic in the code; I changed the sample scripts, attached,
and it would be nice if you all could give it another round (thanks to
everyone who already did!) in particular to those having an upstart
init system.

Cheers,
