dpkg-reconfigure 中的“-plow”選項有什麼作用

我在 Unix stackexchange 上偶然發現了以下答案-plow，該選項與 一起使用dpkg-reconfigure，但我在 dpkg 或 dpkg-reconfigure 聯機幫助頁中找不到任何關於它的資訊：

• http://man7.org/linux/man-pages/man1/dpkg.1.html
• http://manpages.ubuntu.com/manpages/cosmic/en/man8/dpkg-reconfigure.8.html

那麼這個選項到底在做什麼呢？我聞起來像貨物崇拜。

從您連結的手冊頁dpkg-reconfigure：

**-p***值*，**--優先級**=*值*
指定將顯示的問題的最低優先級。dpkg-重新配置
無論您的預設優先級是什麼，通常都會顯示低優先級的問題。看
  [debconf](http://manpages.ubuntu.com/manpages/cosmic/en/man7/debconf.7.html) (7) 獲取列表。

從man 7 debconf：

Another  nice feature of debconf is that the questions it asks you are prioritized. If you
don't want to be bothered about every little thing, you can set up debconf to only ask you
the most important questions.  On the other hand, if you are a control freak, you can make
it show you  all  questions.  Each  question  has  a  priority.  In  increasing  order  of
importance:

low    Very  trivial  questions  that have defaults that will work in the vast majority of
      cases.

medium Normal questions that have reasonable defaults.

high   Questions that don't have a reasonable default.

critical
      Questions that you really, really need to see (or else).

Only questions with a priority equal to or greater than the priority you  choose  will  be
shown  to  you. You can set the priority value by reconfiguring debconf, or temporarily by
passing  --priority=  followed  by  the  value  to  the  dpkg-reconfigure(8)   and   dpkg-
preconfigure(8) commands, or by setting the DEBIAN_PRIORITY environment variable.

因此，-plow將顯示所有問題，而不管其他地方可能設置了什麼預設值。這可能是你想要的（當我跑步時，這通常是我dpkg-reconfigure想要的）。
