This worked for me

    options:
      backup:
        exclude:
        - /mnt/3
        - /mnt/2
        - /mnt/1
      forget:
        keep-last:
        - 10
        forgetoption: prune

For me, the line with forgetoption was automatically inserted by autorestic, after I initialized a new repository. I could also solve the issuet temporarily, by removing the whole line completely from the .autorestic.yml. But the issue reappears when initializing the next repository.

Is this intended behavior? And where is the documentation on this forgetoption. Is this to be found in the docs of autorestic, or of restic itself?

Also, on a side note: I am using comments and extra spacing in my .autorestic.yml to make it more understandable and managable, but all of this is removed with the next repository initialization. Is this intended behavior?
