MANUAL UPGRADE INSTRUCTIONS
===========================
This database update will convert policy and build queues to regular suites.
For these archives will be created under Dir::Base:
NEW: <base>/new
policy queues: <base>/policy
build queues: <base>/build-queues
Please add Dir::Base to dak.conf and try the update again. Once the database
upgrade is finished, you will have to reprocess all uploads currently in
policy queues: just move them back to unchecked manually.
