I am very fuzzy on this now, but I think this is basically that there is
automatic code to use the old location if it exists, and otherwise the
new location (location of record / correct location), and that use of
automatic mechanisms is not clearly robust against config changes.

It doesn't matter where the build server stores package files, but I
think PKG_DBDIR gets compiled into package-management tools so this
could result in a pkgin and pkg_install that operates in /var/db/pkg.

It still seems needed to me.   My view is more or less (and I think this
is all #if NetBSD):

  - a system with /var/db/pkg that is not explicitly configured to use
    it (mk.conf and pkg_install.conf both) is misconfigured

  - packages built on a system configured with /var/db/pkg should not be

  - supported versions (8/9/current) of NetBSD should not vreate
    /var/db/pkg on installation.  Maybe that's already true.

  - Existing machines used for package building should be migrated to

  - Probably the warning/check should be changed to:

      * If both /var/db/pkg and /usr/pkg/pkgdb exist, error out with a
        pointer to  Same for
        /var/db/pkg and a differing PKG_DBDIR.   This is basically
        "fatal error on split brain pkgdb".

      * If /var/db/pkg exists and PKG_DBDIR is not set to /var/db/pkg,
        error as above, but change message to "Package database found in
        old location /var/db/pkg and PKG_DBDIR is not set."  with
        pointer to (new?) section in pkgdb-change.

but I am a bit foggy, having recovered from the pain of dealing with
this last December.
