+/**
+ * FilesystemPersister persists channel data on disk, where each channel's
+ * data is stored in a file named after its funding outpoint.
+ * 
+ * Warning: this module does the best it can with calls to persist data, but it
+ * can only guarantee that the data is passed to the drive. It is up to the
+ * drive manufacturers to do the actual persistence properly, which they often
+ * don't (especially on consumer-grade hardware). Therefore, it is up to the
+ * user to validate their entire storage stack, to ensure the writes are
+ * persistent.
+ * Corollary: especially when dealing with larger amounts of money, it is best
+ * practice to have multiple channel data backups and not rely only on one
+ * FilesystemPersister.
