There are 65 files in /var; I don't think that's excessive ;-)

I don't think so; I noticed the problem right after having installed
NetBSD using sysinst.  However, since I reran newfs(8) on the file
system and restored its contents (using pax(1)), df(1) now reports the
expected value.  Hmm.

If I find enough time I'll reinstall using sysinst, just to see if I can
reproduce the problem.
