   6    DPKGv1 Data Base Implemenation
   7
   8    The DPKGv1 database is typically stored in /var/lib/dpkg/. For
   9    DPKGv1 the 'meta' information is the contents of the .deb control.tar.gz
  10    member prepended by the package name. The meta information is unpacked
  11    in its temporary directory and then migrated into the main list dir
  12    at a checkpoint.
  13
  14    Journaling is providing by syncronized file writes to the updates sub
  15    directory.
