Because ${DISTDIR} is, by definition, writable, and you can't say that
about any other directory that I can think of in pkgsrc (and, besides,
we were on a read-only pkgsrc kick at the time).

/var/db was originally meant to be for runtime database files, like
the kvm "database", and was not meant to be for persistent storage. 

The bit you quote above was added at a later date (January 2004, in
revision 1.59), to rationalise the choice that had already been made
for us when we imported the pkgsrc system from FreeBSD.  Specifically,
I added the text

	...and persistent files used in the maintenance of third party

(related to /var/db/pkg).  But I still don't think that PKG_DBDIR
defaults to the right place, according to the hier(7) as it used to

I'm still less than enthusiastic about using /var to store persistent
databases, but I customise ${PKG_DBDIR} anyway.
