Yes, I think that's a reasonable assumption.

There was whinging that it took a "long time" to run svnversion on the
whole src tree, so a very badly formed patch was applied to try and
conditionalize it for only running when the kernel is being built.
This change will actually restrict it to when the kernel is being
built in a directory called */sys/* which will actually work for the
vast majority of FreeBSD users.

Knock yourself out, I look forward to reviewing your patches.

This very simple little item has already received WAY more hackery
than it really merits. The only reason I made the change I did (after
swearing off touching it again on the principle of trying to avoid
getting bike shed paint all over my clothes) was that the patch that
was applied previously was just plain silly.

FWIW, your comments would have been a lot more timely if they had been
in response to my posting this patch following the discussion on the
topic in -current on 8/15. Given that I have received no comments on
that post at all in the 7 days since posting the patch I felt it was
more than reasonable to commit it tonight.
