Enabling AppArmor on Arch Linux

This document describes the steps taken to enable AppArmor on an Arch Linux system by modifying the GRUB configuration.

Steps to Enable AppArmor

Check Current GRUB Configuration:
```
cat /etc/default/grub
```
Identify the line starting with GRUB_CMDLINE_LINUX_DEFAULT.

Edit the GRUB Configuration:

sudo nano /etc/default/grub

Modify the GRUB_CMDLINE_LINUX_DEFAULT line to include AppArmor parameters:

GRUB_CMDLINE_LINUX_DEFAULT="nowatchdog nvme_load=YES rd.luks.uuid=1789a726-8a00-4985-bf32-3a45751d5219 rd.luks.uuid=4a3498f7-9c99-4979-9b41-1a720bae32e1 resume=/dev/mapper/luks-4a3498f7-9c99-4979-9b41-1a720bae32e1 apparmor=1 security=apparmor"

Save and Exit:
In nano, press CTRL + X, then Y, and then Enter to save the changes.

Update GRUB:

sudo grub-mkconfig -o /boot/grub/grub.cfg

Reboot the System:
```
sudo reboot
```
Check AppArmor Status:
```
sudo aa-status
```
Verify that AppArmor is now active and functioning correctly.

A few things to keep in mind:

All of my work comes with absolutely no warranty, expressed or implied. However…

It will almost certainly work until it breaks,
though I must admit it may never work or be useful—and that would be sad.

If/when it breaks, you can keep all the pieces.

As for what you don’t like, it’s yours to do with as you will.

If you find my materials helpful, both you and I will be happy (at least for a while).

My advice is worth every penny you paid for it!
