1. theoretically, the installation process cannot be interrupted, but in fact, during the process of compiling the software package, C can continue next time. Every time emerge completes a software package, it will automatically record relevant information and install it into the system. Because this package has a complete process, the next continuation will be recompiled and installed from the broken package. However, software packages are interdependent. After the software package is upgraded, the interface may change, which may cause problems in some programs. If the problem happens to be emerge and related things, such as python, it must be dead.

2. When you are disconnected from the network, you can still continue compiling. But without the downloaded source code, there is no way to download it.

3. If there is no networking, you need to download the data of portage and the corresponding software source code in advance for compilation.

You need a chroot environment, so you must have a Linux system. This system can be started in any way, as long as it can start to the Linux command line and read where you need to install it. Just like when you install Windows, you need to start an installation environment, that is, the installer interface for installing Windows (Ghost version means starting into Ghost).
