Linux

Linux from scratch is not really a Linux system but a method to build from almost nothing an entire system.

The purpose is highly educative for who wants to understand what are the different layers which are composing a modern Linux/Unix operating system.

This is very simple.

Press ALT+F2 and type xterm followed by ENTER.

A shell is opening so you can type :

sudo passwd root

Then type your password once, followed by the password you want to set up for the root user twice.

1. Stability

   Some linux servers are not restarted for years, for data operations continuity is essential, this more than what people are used to.

2. Safety

   As long as you apply your security updates in time, you'll be almost quiet with anything else. No heavy antivirus to run periodically.

3. Cheap to get

   You just have to download it from internet and burn a Cd with it.

4. Longer life cycle of hardware

   You were thinking about putting those old pentium 133 in the trash ?
