                       for the harware that requires non-default partition system ids. The parameter

+         --mkfs-extraopts: This option specifies extra options to pass to mkfs utility.
+                           NOTE, that wic uses default options for some filesystems, for example
+                           '-S 512' for mkfs.fat or '-F -i 8192' for mkfs.ext. Those options will
