Henri, I'm sure you know more about how CPE is actually used than most
of us. In your opinion, would a partial result like
cpe:/o:microsoft:windows_xp be useful to people (better than nothing),
or are they going to want more precise information like
cpe:/o:microsoft:windows_xp::sp3.

It seems like offering even a little bit of information is useful, but
if someone has the CPE hooked up to a vulnerability database or
something, they may not want to see spurious alerts about Windows XP
when the OS is actually Windows XP SP3 and already has the vulnerability
fixed.

I'm trying to get information on whether it would be better to at first
implement very easy, but incomplete, CPE (like the cpeify-os.py script);
or if the output needs to be mostly complete to begin with.

From the OpenVAS point of view, it is already very helpful to have partial
information! Therefore I'd very welcome to have a first simple implementation
which we can use to test/build the full chain up to vulnerability management
database.
It is task of the management tool to deal with incomplete CPE information.

FWIW: I don't think in this regard there exists no "incomplete CPE", just
"incomplete CPE information". AFAIKT, CPE was designed to work even with
incomplete information.
