+   DPKGv1 Data Base Implemenation
+   
+   The DPKGv1 database is typically stored in /var/lib/dpkg/. For 
+   DPKGv1 the 'meta' information is the contents of the .deb control.tar.gz
+   member prepended by the package name. The meta information is unpacked
+   in its temporary directory and then migrated into the main list dir
+   at a checkpoint.
+   
+   Journaling is providing by syncronized file writes to the updates sub
+   directory.
