The opti *X-mount.nocanonicalize*[**=**_type_]:: Allows disabling of canonicalization for mount source and target paths. By default, the `mount` command resolves all paths to their absolute paths without symlinks. However, this behavior may not be desired in certain situations, such as when binding a mount over a symlink, or a symlink over a directory or another symlink. The optional argument _type_ can be either "source" or "target" (mountpoint). If no _type_ is specified, then canonicalization is disabled for both types.
