GetDriver initializes and returns the registered driver.

GetFSMagic returns the filesystem id given the path.

IsDriverNotSupported returns true if the error initializing the graph driver is a non-supported error.

IsInitialized checks if the driver's home-directory exists and is non-empty.

Mounted checks if the given path is mounted as the fs type.

New creates the driver and initializes it at the specified root.

NewDefaultChecker returns a check that parses /proc/mountinfo to check if the specified path is mounted.

NewFsChecker returns a checker configured for the provided FsMagic.

NewNaiveDiffDriver returns a fully functional driver that wraps the given ProtoDriver and adds the capability of the following methods which it may or may not support on its own: Diff(id, parent string) (archive.Archive, error) Changes(id, parent string) ([]archive.Change, error) ApplyDiff(id, parent string, diff archive.Reader) (size int64, err error) DiffSize(id, parent string) (size int64, err error).

NewRefCounter returns a new RefCounter.

Register registers an InitFunc for the driver.

ErrIncompatibleFS returned when file system is not supported.

ErrNotSupported returned when driver is not supported.

ErrPrerequisites returned when driver does not meet prerequisites.
