# HG changeset patch # User Jim Unroe rock.unroe@gmail.com # Date 1482018748 18000 # Node ID 670eebb40b785a1537d66a61067d80107d9363bf # Parent b6d25de71e0feb5aed26105b5d5d8edddfcb8b66 [RT22] Add Retries When Initializing Cloning

Cloning does not always begin on the initial request. This patch adds the ability to retry up to five times (similar to how the factory software does it).
