+
+A simple optimization has been carried out:
+
+* The update source has been modified
+* The problem of garbled characters has been solved
+
+In order to have greater flexibility:
+
+* The disk partition adopts LVM support
+This is convenient for subsequent expansion and the current size of the entire kali disk is 20 GB
+
+Tip: Remember to fix permissions after importing
