Title:
  Retracer caching strategy uses too much disk space

Status in “whoopsie-daisy” package in Ubuntu:
  Confirmed

Bug description:
  The problem is each retracer per arch per distro has its own temp
  directory.

  We currently run 4 restracers for 2 architectures
  I am seeing  7 distros: elementary 0.2  LinuxMint 12  nagios  Ubuntu 10.04  Ubuntu 11.04  Ubuntu 11.10  Ubuntu 12.04  Ubuntu 12.10
  Each  temp directory is around  ~10G

   4 x 2 x  7 x ~10GB > 500 GB

  Or current disk capacity is 268 GB

  The retracer may not have a temp dir in each distro but it potentially
  can grow to that extent without human intervention.

  Can we think of ways to reuse cache directories more eficiently or
  clean up unused distros after time?
