 By adding to the request keys like ``-sla-kedifa-<key>`` it is possible to provide SLA information for kedifa partition. Eg to put it on computer ``couscous`` it shall be ``-sla-kedifa-computer_guid: couscous``.
 
+Also ``-kedifa-software-release-url`` can be used to override the software release for kedifa partition.
