ssh identity handling
The official documentation says:
"The third command uses SSHFS and the user credentials are omitted (it logs in as the current user and authenticates he/she by the key which must be preconfigured in /etc/config/schnapps or ~/.ssh/config or added to the running ssh-agent)."
But the /etc/config/schnapps does not have effective options to setup user identity key for ssh session (username and password is ignored, identity file option does not exists.), the second option ~/.ssh/config needs exact configuration non-intuitively matching to url in the /etc/config/schnapps config.
Expected behaviour is there will be an option for identity file or username in /etc/config/schnapps does not been ignored. I thing the signing in to remote server as root to backup snapshots is very rare option.
