Take today, I reinitialised my VPS and this time, the first thing I did was:

- `sudo apt update && sudo apt upgrade -y`
- then I installed important pkgs: podman (yeah, I took you guys advice and went for a podman quadlet setup), git, tmux (was already installed), cryptsetup, and others
- then I `fallocate -l 30G /secure`
- then `cryptsetup luksFormat /secure` to establish the cryptographic boundary
- then `cryptsetup luksOpen /secure vault` and formatted the mapped volume with mkfs.ext4
- I mounted the decrypted block to my application directory to serve as an isolated persistence layer for my data
- wrote the declarative .container, .network, and .volume Quadlet files for my routing and vault services, dropping them into ~/.config/containers/systemd/
- executed systemctl --user daemon-reload and my (semi-)self-hosted service were ready.

So much 'then' 😂

First time I went through to CompTIA Linux+ course, I just went through it, in order to pass the exam. And then I took a test ... to test my newly acquired knowledge (before going for the real exam). I scored below 600 😞.

So I have decided to go through it from the beginning again, this time I want to do it slowly (which to me seems stupid, as I need a certification to begin submitting applications... I am running on fumes now), and familiarise myself with each linux tool, what they do, when they should be used, and how they should be used.
