pre_distupgrade.

 * Update README to reflect that piuparts runs fine in etch. 

  - Implement Chroot.create_temp_tgz_file() (since it's used in the VirtServ
    subclass)
  - Fix a typo -- chroot.create_temp_tgz() was being called instead of
    chroot.create_temp_tgz_file() (Closes: #465416)

Oops. chmod does not honor umask (I'm so stupid people who've never even heard of me pity me), so don't use 0666, use 0644 instead.

Make the summary files world-readable. tempfile makes them not be world-readable, and there's no reason for them not to be, since the log files are.
