+## Unmounting bug
+
+Sometimes the root file system is not unmounted cleanly
+even when the `halt` command is used to shutdown the system.
+Therefore we recommend you use the following command:
+
+    $ sync
+
+and wait a few seconds before issuing the `halt` command.
+An `fsck` may still be triggered on the next boot,
+and you may encounter the [[open_issues/e2fsck_i_file_acl_hi]] bug,
+but these errors are harmless.
