- Investigation of previous attempt showed that the use of 'alternatives' was not going to work here
- Pulled out all 'alf_usage_delta' creations from other upgrade scripts
- Removed alternatives from patch 'patch.db-V3.4-UsageTables'
- Added '--(optional)' at various locations to keep things sane
- Tested 2.1.7, 2.2.x and clean bootstrap on MySQL
