+ help
+ Composefs is a filesystem that allows combining file content from
+ existing regular files with a metadata directory structure from
+ a separate binary file. This is useful to share file content between
+ many different directory trees, such as in a local container image store.
+
+ Composefs also allows using fs-verity to validate the content of the
+ content-files as well as the metadata file which allows dm-verity
+ like validation with the flexibility of regular files.
+
+ For more information see Documentation/filesystems/composefs.rst
+
+ If unsure, say N.
