Serhiy Storchaka added the comment:
The readlink utility has different modes for canonization:
-f, --canonicalize
canonicalize by following every symlink in every component of the
given name recursively; all but the last component must exist
-e, --canonicalize-existing
canonicalize by following every symlink in every component of the
given name recursively, all components must exist
-m, --canonicalize-missing
canonicalize by following every symlink in every component of the
given name recursively, without requirements on components existence
I think every mode has use cases.
