 *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. This mount option does not affect the conversion of source tags (e.g. LABEL= or UUID=) and fstab processing.

-The command line option *--no-canonicalize* overrides this mount option and affects all path and tag conversions in all situations, but it does not modify flags for open_tree syscalls.

+The command-line option *--no-canonicalize* overrides this mount option and affects all path and tag conversions in all situations, but for backward compatibility, it does not modify open_tree syscall flags and does not allow the bind-mount over a symlink use case.

 Note that *mount*(8) still sanitizes and canonicalizes the source and target paths specified on the command line by non-root users, regardless of the X-mount.nocanonicalize setting.
