link_cow

  • link_cow=true|false
  • Defaults to false

This feature offers similar functionality to what cow-shell offers.

When enabled if mergerfs is asked to open a file to write and the link count on the file is greater than 1 it will copy the file to a temporary new file and then rename it over the original. This will atomically "break" the link. After that it will open the new file.
