 One defines their mounts in `mounts.conf`, giving for each:
 * the mapper name (usually defined in `/etc/crypttab`);
 * the mount target path;
+* the file system type;
 * a friendly name for the mount (optional);
-* a boolean for enabling auto-locking (i.e. closing encrypted volume when unmounted) or not.
+* a boolean for enabling auto-locking (i.e. closing encrypted volume when unmounted) or not;
+* a boolean for enabling mount timeout (useful to prevent hanging at boot).
 
 The install script then generates a Systemd mount file for each mount, with the required bindings.
 
 ### Files
 * `template.mount` is a template for Systemd mount units.
 * `close-vault.conf.template` is a Systemd drop-in template, for auto-locking.
+* `timeout.conf` is a Systemd drop-in for mount timeout.
 #### Installation
 * `mounts.conf.template` contains a mount definition example, and should be copied locally in `mounts.conf.d`
   as `<something>.conf`, for each of your mounts.
