Okay, just reassuring that we're on the same page.

See, this is exactly my problem: who is it notifying?
If it prints the notice to a printer, it's notifying the site administrator.
If it prints to HTML, it's notifying the users of the website.
The former is reasonable to me, at least as far as the GPL goes. (However,
PHPNuke and Apache are clearly (I hope) not being started interactively wrt
the site admin, so these notices shouldn't be mandatory.)
The latter is the case I dislike. I think of website users using the
website (and only very distantly and nebulously are they in any way
users of PHPNuke), and the administrator as the user of PHPNuke.

I mean that the idea is that PHPNuke (run by Apache) and "sort" (in the
middle of a shell pipeline) are equally interactive. Neither talks
directly to the user; they go through other programs. So, if
that argument is bought, then we have two choices: either sort(1)
outputting a mandatory GPL blurb on startup is DFSG-free (gross), or
PHPNuke outputting a mandatory GPL blurb to HTML is DFSG-unfree. (And,
in parallel, either sort(1) outputting a GPL blurb would be mandatory,
or PHPNuke outputting one would be optional.)
Like I said, I havn't been completely convinced of this.
(Determination of whether "df" is interactive is tangental to this,
though I'm not uninterested in reaffirming the notion that it is not.
Determining the interactiveness of "cat" in a pipeline would be
relevant only if we agreed to the above.)

Oops. Once we start using the word "technically", we're getting outside
the realm that licenses should care about ...
 ignoring the common case where the system admin and the site admin are
two different people and the site admin has no physical access to the machine
 however, in this case we go back to the WU situation: a copyright
holder's strange interpretation rendering a normally free license non-free.
This would be annoying, since it would probably be the first time a GPL
program was declared DFSG-unfree (and we might hear rumblings from the
hopefully small DFSG#10-as-grandfather-clause crowd) ...
