Comment 8 for bug 1068917

Yes:

1. I installed the package in a lucid schroot (buildd variant)
2. configured to listen on a unique port (3143 vs. default 3142)
3. configured another system to use it as an apt proxy (Acquire::http { Proxy "http://schroots-ip:3143/"; }; )
4. pulled an apt-get update from the second system
5. attempted apt-get dist-upgrade (no new packages were available)
6. validated that ACNG's cache in the schroot was populated

   (pbuild22749)root@dark-passenger:/var/cache/apt-cacher-ng# du -hsc *
   28K archive.canonical.com
   124K ppa.launchpad.net
   96K security.ubuntu.com
   13M uburep

I observed no errors during install or operation.
