Is there any way to install rclone on the host? There's two projects for using rclone in kubernetes, but one relies on rclone being on the host, and the other can't handle anything that uses a login token that changes, since it uses a secret for storing the config and it can't be changed by the csi plugin so I'd have to basically rewrite the secret manually twice a day... And that's not happening >_<

You can if you build your own version of k3os and customize what's installed inside. Otherwise, good luck 🙂 FYI this OS has been abandonned by Rancher/SUSE and its maintainer has left the company.
