我假设以“<”开头的行意味着我需要删除这些行，而以“>”开头的行意味着我需要添加这些行。这个 diff 补丁应该应用于 session_manager_setup.sh；但是，我的 session_manager_setup.sh 看起来是这样的，所以这个补丁似乎已经过时了：

我该如何将此补丁应用于最新版本的 session_manager_setup.sh？
答案1
（我意识到这个问题已经很老了，但仍然没有答案......）
除非你处于开发者模式并已挂载 rootfs，你不能。
注意：如果以可写模式挂载根文件系统，即使您不做任何更改，它也将不再可验证，并且当您切换回正常模式时，您必须使用恢复映像来恢复系统。
如果你曾经或正在继续阅读。如果你对如何编辑感到困惑/sbin/session_manager_setup.sh，那么你真的不应该这样做。这是对铬的严重修改，会导致东西损坏。
