config/types: allow deleting partitions by label - #2292
Conversation
Partitions can be addressed by Number or by Label. When a user wants to delete a partition, they set ShouldExist: false and identify it. Previously, the validation logic incorrectly included the Label field in the forbidden-fields list when ShouldExist is false, making it impossible to delete a partition by label. This commit removes Label from that validation check.

What this PR does / why we need it:
This PR fixes a validation bug that prevented users from deleting a disk partition by referencing its label.
In Ignition, partitions can be addressed either by their
Numberor by theirLabel. When a user wants to delete a specific partition, they setshouldExist: falseand identify the partition. However, the validation logic incorrectly included theLabelfield in the "forbidden-fields" list whenshouldExistis false. This made it impossible to delete a partition by label, as the validator would incorrectly reject the configuration withErrShouldNotExistWithOthers.This PR removes
Labelfrom that specific validation check across bothv3_6andv3_7_experimentalconfig schemas, acknowledging that the label serves as an identifier rather than a conflicting property.Fixes:
(Add the related issue number here if you opened an issue for this, e.g.,
Fixes #XYZ)Special notes for your reviewer:
ShouldExist: falsenow properly validates when aLabelis provided.ErrShouldNotExistWithOthersstill correctly fires ifTypeGUID,GUID,StartMiB, orSizeMiBare specified alongsideShouldExist: false.
