CLI - Create parameterized namespace

[JonnyBDev]

Problem

While using the CLI to bootstrap a new Flux installation on the cluster you can use different parameters to configure the installation. One parameter is --namespace <string:flux-system>. Starting the process without this parameter will automatically create the namespace flux-system. If you define a namespace like --namespace <flux-system> it won't create the namespace and abort the installation with a timeout:

✚ generating manifests
✔ manifests build completed
► installing components in flux-system namespace
✗ install failed: timeout waiting for: [Namespace/flux-system status: 'NotFound']

The flux install --help clearly states that it will install Flux in a namespace If present (If present, the namespace scope for this CLI request (default "flux-system")). The behavior of Flux is absolutely correct.

Suggestion

My suggestion would be to check if a namespace, configured via a parameter, exists. If yes, install it. If not, create the namespace like you would without the parameter, and continue the installation. This would improve the UX and a manual creation is not needed.
