- * are not {@link #isApplicable(Volume) applicable} for the Vault/Volume. The Volume must
- * check whether a MPC is applicable by invoking {@code #isApplicable(Volume)} on it
- * <i>before</i> calling {@code #chooseMountPoint(Volume)}.
- *
- * <p>At execution of a MPC {@link #chooseMountPoint(Volume)} is called to choose a mountpoint
- * according to the MPC's <i>strategy.</i> The <i>strategy</i> can involve reading configs,
- * searching the filesystem, processing user-input or similar operations.
- * If {@code #chooseMountPoint(Volume)} returns a non-null path (everything but

- * <p>If {@code #chooseMountPoint(Volume)} yields no result, the next MPC is executed

- * If the {@code #prepare(Volume, Path)} method of a MPC fails, the entire
- * Mountpoint-Choosing-Operation is aborted and the method should do all necessary cleanup
- * before throwing the exception.
