Configuration

AppArmor¶

As there are a lot of rules, it is recommended to enable caching AppArmor profiles. In /etc/apparmor/parser.conf, add write-cache and Optimize=compress-fast.

echo 'write-cache' | sudo tee -a /etc/apparmor/parser.conf
echo 'Optimize=compress-fast' | sudo tee -a /etc/apparmor/parser.conf

Info

See Speed up AppArmor Start on the Arch Wiki for more information:

Personal directories¶

Danger

You need to ensure that all personal directories you are using are well-defined XDG directory. You may need to edit these variables to your own settings.

This project is designed in such a way that it is easy to personalize the directories your programs have access by defining a few variables.

The profiles heavily use the (largely extended) XDG directory variables defined in the Variables Reference page.

XDG variables overview

See Variables Reference page for more.

Description	Name	Value
Desktop	`@{XDG_DESKTOP_DIR}`	`Desktop`
Download	`@{XDG_DOWNLOAD_DIR}`	`Downloads`
Templates	`@{XDG_TEMPLATES_DIR}`	`Templates`
Public	`@{XDG_PUBLICSHARE_DIR}`	`Public`
Documents	`@{XDG_DOCUMENTS_DIR}`	`Documents`
Music	`@{XDG_MUSIC_DIR}`	`Music`
Pictures	`@{XDG_PICTURES_DIR}`	`Pictures`
Videos	`@{XDG_VIDEOS_DIR}`	`Videos`
Books	`@{XDG_BOOKS_DIR}`	`Books`
Projects	`@{XDG_PROJECTS_DIR}`	`Projects`
Screenshots	`@{XDG_SCREENSHOTS_DIR}`	`@{XDG_PICTURES_DIR}/Screenshots`
Sync	`@{XDG_SYNC_DIR}`	`Sync`
Torrents	`@{XDG_TORRENTS_DIR}`	`Torrents`
Vm	`@{XDG_VM_DIR}`	`.vm`
Wallpapers	`@{XDG_WALLPAPERS_DIR}`	`@{XDG_PICTURES_DIR}/Wallpapers`

You can personalize these values.

First create the directory /etc/apparmor.d/tunables/xdg-user-dirs.d/apparmor.d.d:

sudo mkdir /etc/apparmor.d/tunables/xdg-user-dirs.d/apparmor.d.d

Then create a local addition file in it where you define your own personal directories. Example:

@{XDG_VIDEOS_DIR}+="Films"
@{XDG_MUSIC_DIR}+="Musique"
@{XDG_PICTURES_DIR}+="Images"
@{XDG_BOOKS_DIR}+="BD" "Comics"
@{XDG_PROJECTS_DIR}+="Git" "Papers"

Then restart the AppArmor service to reload the profiles in the kernel:

sudo systemctl restart apparmor.service

Examples

For git support, you may want to add your GO_PATH in the XDG_PROJECTS_DIR:
```
@{XDG_PROJECTS_DIR}+="go"
```
If you use Keepass, personalize XDG_PASSWORD_STORE_DIR with your password directory. Eg:
```
@{XDG_PASSWORD_STORE_DIR}+="@{HOME}/.keepass/"
```
Add pacman integration with your AUR helper. Eg for yay:
```
@{user_pkg_dirs}+=@{user_cache_dirs}/yay/
```

Local profile extensions¶

You can extend any profile with your own rules by creating a file in the /etc/apparmor.d/local/ directory with the name of your profile. For example, to extend the foo profile, create a file /etc/apparmor.d/local/foo and add your rules in it.

Example

child-open, a profile that allows other program to open resources (URL, picture, books...) with some predefined GUI application. To allow it to open URLs with Firefox, create the file /etc/apparmor.d/local/child-open with:
```
  @{bin}/firefox rPx,
```

Note

This is an example, no need to add Firefox into child-open, it is already there.

Info

rPx allows transition to the Firefox profile. Use rPUx to allow transition to an unconfined state if you do not have the profile for a given program.

Then, reload the AppArmor rules with sudo systemctl restart AppArmor.
