Package: dpkg
Version: 1.10.20
Severity: normal

For low memory (or embedded systems), dpkg should not load the available 
packages into memory.  For the stable distribution, this takes up nearly 
11MB and made it difficult to upgrade my system -- upgrading libc6 
terminated due to memory constrains.  I was able to install my packages 
by commenting out all sources...

My embedded system is a PowerPC with 32MB of ram using a NFS root for 
development.

Thanks,
-Paul

I don't think the memory requirements are in any effect actual problems
at this point in time. But this got fixed back in dpkg 1.17.11, but the
bug was not closed then, I've added the closure to the changelog
locally now. Here's the relevant entry:

  ,---
  dpkg (1.17.11) unstable; urgency=low

    [ Guillem Jover ]
    …
    * Do not write to the available file when unpacking binary packages. This
      information is not useful as dpkg has never recorded the archive path,
      so it has never been truly available for re-installation anyway.
      Closes: #241768
    …

There were previous versions to make dpkg-query too not load the
available database by default.

Thanks,
Guillem
