-====== Internal and External Servers Operating System ======+====== A) Gentoo Linux Installation ======
  
-The **internal** server should be Gentoo. If you prefer a different distribution, go ahead, but you will need to adapt all the future instruction as i will use Gentoo.+Why [[https://www.gwntoo.org|Gentoo Linux]]? In short, because its lightweight, gives you full control on your server and can be much more secure than others bloated Linux distributions. More in detail.
  
-The **external** server again should be Gentoo, but specially on VPSs you might not have freedom of choice. As far as it's a reliable Linux distribution, you should be fine. After all, you will only run tunnels on it.+These instructions are aimed at supporting you during the installation of your home server, the one on which most, or all, your self-hosted home services will run. This same page can be referred to when installing your //external// server(s), provided they don't already come pre-installed with some other flavour of Linux.
  
-All the following applies to the //internal// server. Most of it also the //external// server, if you are installing Gentoo there too. +This is not meant to be an exustive guide, as there are plenty of good resources on the topic, specially the amazing [[https://wiki.gentoo.org/wiki/Handbook:AMD64|Gentoo Handbook]] which is the Gentoo Bible for installation.

-Why [[https://www.gwntoo.org|Gentoo Linux]]? Because its lightweight, gives you full control on your server and can be much more secure than others bloated Linux distributions.+
  
 When installing Gentoo Linux you have the total freedom to choose any single piece of the system, including whether to install or not a Cron Daemon and even a logger daemon. No other distro gives you so much freedom. Moreover, while you can use SystemD and NetworkManager with Gentoo, you are **not** forced to use them, and in fact specially for small servers, they might both be unneeded. When installing Gentoo Linux you have the total freedom to choose any single piece of the system, including whether to install or not a Cron Daemon and even a logger daemon.

 Installing Gentoo Linux is less difficult than you might think. The great [[https://wiki.gentoo.org/wiki/Handbook:AMD64|Gentoo Handbook]] is very well written and also fairly easy to follow if you don't rush it. I assume you are capable of following it up until you can boot a text-only system. Installing Gentoo Linux is less difficult than you might think.

 +I will assume your home server has one drive dedicated to the Gentoo installation. Data, media, and other files will be stored on a separate RAID array of some kind.
 +
 +Please do not configure that RAID array now, but read the [[gentoo:storage|Storage Setup]] page.
