And yet, we've been at this for weeks now...

Not sure why that matters.  Never heard a definition like that
before.  Got any citation?

Sure it does.  is changes where waf installs the resultant files.

FHS, and distro policies, say where that can be.

I'm still totally confused by what you mean as 'system configured'???

I'm also totally confused as to what that has to do with where the
files get installed to by waf, which is all I care about.

Uh, lost me.  Is that a technical term?

Yeah, and all NTPsec cares about is DESTDIR.  What a packager does
after that is none of our business.  It is none of our biz wahat
happens after waf install.

Anything that happens after waf install is between the packager and his
distro.  Not out problem, as long as we give the packager the bits
he needs.

Really?  I musta been doing it wrong all along.  And a lot of other
folks.

I think we got some terminology issues here.  When I use DESTDIR, I
feel I am 'configuring'.  And I'm still not sure what this has to
do with where waf install things, which is the only issue I care
about.
