编译时#xff0c;系统会自动调用

super.img不需要我们手动操作。

但难免还是有朋友想深入研究下

super.img希望自己手动生成

lpmake

信息包含了所有的选项说明但我相信读到这里的小伙伴只有少部分真正去阅读了工具选项和说明。

主要有几点

说明是英文的一看英文就反感。

没说你我自己就是这样。

选项很枯燥看了也不知道怎么用喜欢手把手的那种详细说明文档

分钟去仔细阅读一下工具所有选项以及相应的说明主要理由有以下几点

不喜欢看英文的文档那是因为你看得太少了需要多看选项很枯燥看了也不知道怎么用还是因为看得太少了不要寄希望与别人的手把手文档有当然好没有就上帮助文档这才是必由之路。

说到底自带的帮助文档是第一手的资料阅读第一手的资料有助于你提高自己的学习能力。

lpmake

工具对学习理解也有很大帮助。

实在理解不了帮助文档那照着别人的用法依葫芦画瓢总比较容易一点。

分区制作镜像时可以提供一样的文件或者像其他分区一样system_b

但为什么这里会传递
