Subject: [PATCH]  /var/lib/pisi altinda duran eski formatli metadata
 dosyalarinizi fix edebilirsiniz bununla (test ettim fakat her ihtimale karsi
 dizini yedekleyin bir yere)..

 bu sayede faik'in pisiye kazandirdigi rebuilddb fonksiyonu ile paket
rootfs0.1'den kalma paketler de db'de guncellenebilir.. bu sayede de ufak bir
kac adim ile rootfs 0.2'nin tar.bz2'sini insanlar indirmek zorunda kalmaz,
sadece binary depodan update edebilirler sistemlerini.. hem biz de update ile
ilgili bir sikintimiz var mi gercek ortamda test etmis olabiliriz belki..
