Foreman » Installer

The flag is called --upgrade-mongo-storage-engine, but the installer sometimes forgets the -engine:

% git grep mongo-storage
katello/hooks/boot/21-mongo_storage_engine.rb:  '--upgrade-mongo-storage-engine',
katello/hooks/pre/30-upgrade.rb:      logger.info 'To upgrade to WiredTiger at a later time run foreman-installer with the --upgrade-mongo-storage flag.'
katello/hooks/pre/30-upgrade.rb:        f << "# Added by foreman-installer during upgrade, run the installer with --upgrade-mongo-storage to upgrade to WiredTiger.\n" 
katello/hooks/pre/31-mongo_storage_engine.rb:  Kafo::Helpers.execute("sed -i -e 's/Added by foreman-installer during upgrade, run the installer with --upgrade-mongo-storage to upgrade to WiredTiger./Do not remove'/g #{hiera_file}")
katello/hooks/pre_validations/30-mongo_storage_engine.rb:    fail_and_exit 'Concurrent use of --upgrade and --upgrade-mongo-storage-engine is not supported. '\
katello/hooks/pre_validations/30-mongo_storage_engine.rb:                  'Please run --upgrade first, then --upgrade-mongo-storage-engine.'
