Bug#661947: apt-get clean deletes /var/cache/apt/*.bin

[Vagrant Cascadian <vagrant@debian.org>]

Package: apt
Version: 0.8.15.9
Severity: normal

when i run apt-get clean, it deletes the files /var/cache/apt/pkgcache.bin and
/var/cache/apt/srcpkgcache.bin.

this also applies to the version in experimental (0.8.16~exp12), but the
version in squeeze (0.8.10.3+squeeze1) doesn't exhibit this behavior.

is this an intentional change? 

removing *.bin causes some issues with copy-on-write root filesystems,
needlessly recreating the *.bin files, though i'm able to reproduce the
behavior on several fairly conventional installs as well.

thanks for the exellence that is apt!

live well,
  vagrant
