Comment 14 for bug 607632

I don't see how very slow dpkg operation on btrfs is a duplicate of dpkg reporting that packages are already configured, especially when the bug this is marked as a duplicate of doesn't mention btrfs at all.
Additionally: It would be good if something could be done to fix this, as because of it a Maverick->Natty upgrade took nearly 24 hours post-download just to unpack and configure packages, which is unacceptably slow.
