Create FreeBSD system custom installation ISO

Www.2cto.com began searching for information and found that there was almost no such information in China. Finally, I learned the rough process from a foreigner's article! The structure of the FreeBSD system is relatively simple. its directory files are basically divided into two categories: 1. the basic system is installed in a location other than/usr/local. 2. install it in the/usr/local path through pkg_add or using the port tree make install. The basic system directly decompress the package and put it in the corresponding directory of the new system. then we can modify the content of the package, directly replace the original content with the modified and customized configuration content, so the newly installed system is exactly the same as the configured system, achieving installation and configuration step by step, improving efficiency, at the same time, repetitive work is also avoided. (As this article is being reviewed in the future, some steps may not be listed after some time.) 1. load the downloaded ISO file to the template system configured in one day, create a storage path for the template system, for example,/var/custom-iso. copy all files in ISO to the directory. Www.2cto.com replaces the configured file with the corresponding file in the decompressed Directory. of course, you can also add files not in the original system, the following is the repackaging and compression process. 1. step cd/8.0-Release-src-filemtree-c-K md5digest-p. /base/> base.tar/base. mtree cd/8.0-Release-src-file/basetar-czpf -. /* | split-B 4 M rm-f .. /base.tar/mv x ?? ../Base.tar cd/8.0-Release-src-file/base.tar find./-type f-depth 1-name 'X ??
