# rename-exdev

If using path preservation and a  `rename`  fails with `EXDEV`:

1.  Move file from  **/branch/a/b/c**  to  **/branch/.mergerfs_rename_exdev/a/b/c**.
2.  symlink the rename's  `newpath`  to the moved file.

The  `target`  value is determined by the value of  `rename-exdev`.

-   passthrough: Return EXDEV as normal.
-   rel-symlink: A relative path from the  `newpath`.
-   abs-symlink: An absolute value using the mergerfs mount point.

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

NOTE: The reason `abs-symlink` is not split into two like `link-exdev`
is due to the complexities in managing absolute base symlinks when
multiple `oldpaths` exist.
