What I don't understand here is: Why wouldn't the $Id$ be updated upon upgrade?
Because it's a manual process?
It MAY not get updated, since $Id$ tags are per-file instead of per-project.
Any sane project will have more than one file, and the file listing the
$Id$ that the end-user sees may not have changed since the last release.
Per-file revision tags are stupid and useless for anything but a one-file
project.
Hmm...:

For a kernel, where development is decentralized, it would make sense: Imageine a
user (or distributor) will nut upgrade anything to the latest version, but only
parts (subsystems). Then the single kernel version number is meaningless.
Not really. They can (and should) create their own version numbers. I can't make
sense of the above output. If you ask a developer to piece together the puzzle
that makes up this subsystem and then fit it into the bigger picture, he won't
love you for it. Not only because this particular subsystem might well be the
same version across several different releases with all their different API's
(the input system has changed its API's incompatibly quite frequently over the
last six months, fe, so a driver-version *alone* in that system makes absolutely
no sense if you're trying to debug it).

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
