| 3 | xyz.openbmc_project.Software.Version. |

| 8 | The priority order specified for the associated Software.Version, |
| 9 | represented as a value between 0 (High) and 127 (Low). Any value |
| 10 | above 127 has implementation-specific purpose. |
| 11 | |
| 12 | Only one Software.Version, per associated device, may be at any |
| 13 | particular priority. A requested priority change may cause other |
| 14 | Software.Versions to change priority. |
| 15 | |
| 16 | A dual-sided redundancy model could be represented by two |
| 17 | Software.Version associations, one of which is at priority 0 and the |
| 18 | other at priority 1. When a new image is Activated, the old |
| 19 | priority-1 association is deleted, the old priority-0 association |
| 20 | becomes priority-1, and the new image is assigned priority-0. |
| 21 | # TODO: Specify "EAGAIN" type error when priority is unable to be modified |
| 22 | # due to current system state. Currently, sdbusplus does not support |
| 23 | # errors on properties. |
