      When using the Agent-based install method, the root device hints now accept links in `/dev/disk/by-path/` as the `deviceName` (in addition to the canonical device in `/dev/`). This allows users to specify a hint that is both stable across reboots and consistent across similar hardware. (link:https://issues.redhat.com/browse/OCPBUGS-13081[*OCPBUGS-13081*])

    Description

      In many cases, the /dev/disk/by-path symlink is the only way to stably identify a disk without having prior knowledge of the hardware from some external source (e.g. a spreadsheet of disk serial numbers). It should be possible to specify this path in the root device hints.
      Metal³ is planning to allow these paths in the `name` hint (see OCPBUGS-13080), and assisted's implementation of root device hints (which is used in ZTP and the agent-based installer) should be changed to match.

          Bug - A problem that impairs or prevents the functions of the product. OCPBUGS-13083 Assisted Root device hints should accept by-path device alias

          • Critical - To be worked on immediately following BLOCKER issues.
          • Closed

          Feature - Capability or a well-defined set of functionality that delivers business value. Features can include additions or changes to existing functionality. Features can easily span multiple teams, and potentially multiple releases. OCPSTRAT-45 Add support for disk id, uuid and path to rootDeviceHints

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.

          Bug - A problem that impairs or prevents the functions of the product. OCPBUGS-13080 Root device hints should accept by-path device alias

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.

          • Normal - To be worked after urgent and high priorities are resolved. This term is chosen when the severity of an issue is relatively close to the level of effort to fix it. The existence of an easily implemented workaround can also lead to this priority level instead of a higher priority.
