* pbuilder-dist:

Browse Source 
- Refactor to use subprocess.popen instead of os.system (LP: #398974)
  - Catch OSErrors when creating directories (LP: #671067)
  - Set HOME so pbuilder reads .pbuilderrc
  - Add bidirectional workarounds for LP: #599695 (pbuilder uses the host
    apt keyring). Complain if the target's keyring isn't installed.
* Use dpkg-vendor in ubuntutools.misc.system_distribution(), cache result.
