+### Description: Do you want to return to the partitioning menu?
+#   You have not selected any partitions for use as swap space. Enabling swap
+#   space is recommended so that the system can make better use of the
+#   available physical memory, and so that it behaves better when physical
+#   memory is scarce. You may experience installation problems if you do not
+#   have enough physical memory.
+#   .
+#   If you do not go back to the partitioning menu and assign a swap partition,
+#   the installation will continue without swap space.
+# 坑的一比
+# 不是确认是否 no_swap
+# 而是 recipe no_swap 时，确认是否返回上一级重新分区
+# 选择 true 就一直死循环
