### 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
d-i partman-basicfilesystems/no_swap boolean false
