+**FilesystemResizeAfterUmount**: This is used for doing offline resize if the
+file system in the last partition is NTFS. This is done after umount and not
+before mounting the file system, because *ntfsresize* (which is used to perform
+the actual resize) will mark the file system as dirty at the end and mounting
+it afterwards is not recommended. This is done in order to force a chkdsk the
+next time Windows boots. Offline NTFS resize is favored on windows-legacy and
+non-windows OSes that do not support online resize. If you want to force
+offline resize on newer Windows systems, the *OFFLINE_NTFSRESIZE* image
+property must be defined.
