link-exdev

If using path preservation and a link fails with EXDEV make a call to symlink where the target is the oldlink and the linkpath is the newpath. The target value is determined by the value of link-exdev.

  • link-exdev=passthrough: Return EXDEV as normal.
  • link-exdev=rel-symlink: A relative path from the newpath.
  • link-exdev=abs-base-symlink: An absolute value using the underlying branch.
  • link-exdev=abs-pool-symlink: An absolute value using the mergerfs mount point.
  • Defaults to passthrough.

NOTE: It is possible that some applications check the file they link. In those cases, it is possible it will error or complain.
