I get warnings when running rke2 server etcd-snapshot

[lindhe]

I have a cluster with the following config.yaml:

etcd-s3: true
etcd-s3-endpoint: s3.example.com
etcd-s3-access-key: <redacted>
etcd-s3-secret-key: <redacted>
etcd-s3-bucket: my-bucket
etcd-s3-region: us-east-1
etcd-snapshot-retention: 20
etcd-snapshot-schedule-cron: '0 */5 * * *'
tls-san:
  - rancher-dev.example.com

When I run the etcd-snapshot command, it warns me that there are unknown flags:

[admin@rancher-node011 ~]$ sudo rke2 etcd-snapshot prune
WARN[0000] Unknown flag --etcd-snapshot-schedule-cron found in config.yaml, skipping
WARN[0000] Unknown flag --tls-san found in config.yaml, skipping

[admin@rancher-node011 ~]$ sudo rke2 etcd-snapshot save
WARN[0000] Unknown flag --etcd-snapshot-schedule-cron found in config.yaml, skipping
WARN[0000] Unknown flag --tls-san found in config.yaml, skipping
INFO[0004] Snapshot on-demand-rancher-node011-1720524031 saved.
INFO[0004] Snapshot on-demand-rancher-node011-1720524031 saved.

The parameters are documented here and they seem to work. What exactly is the etcd-snapshot command warning me for?

Those flags are in your config file, which is parsed by the CLI. The flags are valid for rke2 server but not for rke2 etcd-snapshot, which is why you get a warning.

Any way of running rke2 etcd-snapshot and skip those WARN messages?
