Give yourself little tasks and projects to do. Think of it as being like model kit building. You start with the easy kits like a plane with just a few pieces and as you get better you pick up new things like painting, sanding, and eventually making bigger better kits.

So, start with small things. For example, write a small program with a for-loop and get to know what all if the commands are really doing. This is your basic kit. Add in some variables. Add in user input, and keep going trying new things. Eventually, challenge yourself by learning how to work with a GUI. Sometimes your program will break. This isn’t a bad thing. It teaches you how to debug. What’s important is to take your time and experiment.

Introduction

LXC (Linux Containers) are whole-system containers. They are meant to be able to do just about anything you can do with a VM with a percentage of the system resources and and a tiny startup time.

During Installation:

During installation, you can pretty much choose defaults for everything except you will need to create two additional btrfs subvolumes and if you gave your VM more than 30G of space, you will need to specify that manually because the installer will only recognize 30G by default.

Wait, what?

Why should I patch my server?

Because you won’t get bug fixes.

But my server works just fine, if it’s not broken don’t fix it, right?

What about security fixes?

My server isn’t accessible from the internet. I’m not worried about it getting hacked.

But it’s still possible, right? Do you really want to take that chance?

Yeah, patching requires time and money. It could even require downtime. It’s more important for us to keep the server going than to worry about that stuff. We’re safe.
