Sorry, but that statement is still not sufficient.I want to create something like FuryBSD.
Are you (a) trying to install ONE machine, with something like FuryBSD, or (b) create an installation system similar to FuryBSD (in function) and then distribute it to many machines, perhaps the public?
And: If you want something like FuryBSD, why don't you just install FuryBSD? What does "like" mean in this context? What differences from FuryBSD are you after?
Here is my answer to you: If it is (a), you want to install one machine, then either just install FuryBSD if you want that. If you don't want FuryBSD but instead you want a FreeBSD installation with a GUI, then install FreeBSD, then install the GUI of your choice. On the other hand, if it is (b) you are after, you want to create a new installation system, then that's outside my skill base, and I have no advice on how to do it.
I am happy to answer that question. It is very easy. Read the FreeBSD handbook. It is trivial to find, just a web search for "FreeBSD handbook". When reading it, there are some chapters you can skip, but it will be obvious which ones, because the beginning of each chapter or section explains what its purpose is.I'm thankful if someone tell me step by step. For example, 1- download...2- download... 3- read...
After reading the handbook, installing FreeBSD will be easy. I would actually advice to mix reading, installing and testing. For example, read everything up to the installing section, then grab a computer, and install a text-based (command line) setup, and start using it for a little bit. Once you have experience with that, continue reading about X windows and GUI, and then reinstall. And so on.
