I've tried to create a job to prepull image on the cluster just after Eclipse Che is deployed. Since pulling takes around 15min I don't consider this as good solution....

Another workaround is to pull image locally and copy it to minikube ```bash docker pull ${IMAGE} docker save "${IMAGE}" > universal-developer-image.tar eval $(minikube docker-env) && docker load -i universal-developer-image.tar ```

Yes it can be, but it is basically the same as https://github.com/eclipse/che/issues/21643#issuecomment-1220714353

I tried to mark CheCluster API V1 as unserved but got the following error on the OpenShift: ```yaml requirementStatus: - group: apiextensions.k8s.io kind: CustomResourceDefinition message: CRD is not present name:...

1. I've rechecked the properties above and they are safe to delete.

2. There are bunch of properties in [multiuser.properties](https://github.com/eclipse-che/che-server/blob/b02dc2e9b7c3423d69954f423fa8f90b962f29d3/assembly/assembly-wsmaster-war/src/main/webapp/WEB-INF/classes/che/multiuser.properties) file: * `Che system` section. I believe it can be removed, but we have mentions in [che-docs](https://www.eclipse.org/che/docs/stable/administration-guide/configuring-the-administrative-user/) * `che.system.admin_name` * `che.system.super_privileged_mode` *...

3. With regard to [che.properties](https://github.com/eclipse-che/che-server/blob/b02dc2e9b7c3423d69954f423fa8f90b962f29d3/assembly/assembly-wsmaster-war/src/main/webapp/WEB-INF/classes/che/che.properties) Besides that: Both properties are used to configure [WorkspaceActivityChecker](https://github.com/eclipse-che/che-server/blob/6670c6986b1cb3da5e733e1a0b48db78b393ee3d/wsmaster/che-core-api-workspace-activity/src/main/java/org/eclipse/che/api/workspace/activity/WorkspaceActivityChecker.java#L44) and can be deleted: ``` che.workspace.activity_cleanup_scheduler_period_s che.workspace.activity_cleanup_scheduler_initial_delay_s ``` Both properties are used to configure [TemporaryWorkspaceRemover](https://github.com/eclipse-che/che-server/blob/6670c6986b1cb3da5e733e1a0b48db78b393ee3d/wsmaster/che-core-api-workspace/src/main/java/org/eclipse/che/api/workspace/server/TemporaryWorkspaceRemover.java#L34) and...

BTW, There are some bunch of internal properties which make no sense to expose to end user as well. ``` che.api.* che.websocket.* schedule.core_pool_size db.schema.* ``` I think we can add...
