// RemoveAllOneFilesystemCommon removes the path and any children it contains,

// the first error it encounters. If the path does not exist, RemoveAll
// returns nil (no error).
// It makes sure it does not cross mount boundary, i.e. it does *not* remove
// files from another filesystems. Like 'rm -rf --one-file-system'.
// It is copied from RemoveAll() sources, with IsLikelyNotMountPoint

// RemoveDirsOneFilesystem removes the path and any empty subdirectories it

// cross mount boundaries, i.e. it returns an error rather than remove dirs
// from another filesystem. It removes everything it can but returns the first
// error it encounters. If the path does not exist, it returns nil (no error).
