# My personalized Arch Linux packages

## Build packages from source

Fork this repository.

Then and adjust the following files:
* [pkg/de-p1st-repo/arch-repo.cfg](pkg/de-p1st-repo/arch-repo.cfg)
  * For your build-machine, adjust section `LOCAL MACHINE CONFIGURATION`: Add absolute path of folder [./out](./out) to array `LOCAL_PKG_DIRS`
    as the build packages will be stored there.
  * For your mirror-server, adjust section `REMOTE MIRROR SERVER CONFIGURATION` accordingly.
* [pkg/de-p1st-pacman/pacman.d/de-p1st](pkg/de-p1st-pacman/pacman.d/de-p1st)
  * Add the address of your mirror-server.

Build [de-p1st-repo](pkg/de-p1st-repo) ...

```shell
sudo docker-compose run makepkg de-p1st-repo
```

... and install it on your build-machine and your mirror-server:

```shell
# on your local machine
sudo pacman -U out/de-p1st-repo*.pkg.tar.*

# copy the package to your mirror-server and install it there as well
```

Then you can start building all packages and adding them to your mirror-server:

```shell
./build-pkg-docker.sh
```


## Some notes on arch (meta-)package management

### Managing custom packages; managing a remote repository

1) One could use [crema](https://gitlab.com/mipimipi/crema)
2) Or some self-made shell scripts: [pkg/de-p1st-repo/README.md](pkg/de-p1st-repo/README.md)


## Notes about PKGBUILD

### Package naming

* [package naming](https://wiki.archlinux.org/index.php/Arch_package_guidelines#Package_naming)

Package names are prefixed with `de-p1st` as this is one of my
domains ([p1st.de](https://p1st.de)) which itself is an abbreviation of
[privacy1st.de](https://privacy1st.de)

### Creating config files

```shell
install -Dm644 $src $pkgdir/$dst
```

Example: [pkg/de-p1st-sudo/PKGBUILD](pkg/de-p1st-sudo/PKGBUILD)

### Changing existing config files

* `holo` from the AUR
* [https://github.com/holocm/holo/blob/master/doc/holo-files.8.pod]()

```shell
install -Dm0544 some-config.conf.holoscript "$pkgdir"/usr/share/holo/files/"$pkgname"/etc/path/to/some-config.conf.holoscript
```

Example: 
* [pkg/de-p1st-pacman/pacman.conf.holoscript](pkg/de-p1st-pacman/pacman.conf.holoscript)
* [pkg/de-p1st-pacman/PKGBUILD](pkg/de-p1st-pacman/PKGBUILD)

### Changing config files that are not owned by any package

See [pkg/de-p1st-locale/PKGBUILD](pkg/de-p1st-locale/PKGBUILD) for an example.

### Home skeleton

Pacman should **never** change files in `$HOME`. To still be able to include
customized configurations, one can copy them to the skeleton used for new users:

Files from `/etc/skel` are copied to `/home/$USER` when new users are created.

Example: [pkg/de-p1st-gnupg/PKGBUILD](pkg/de-p1st-gnupg/PKGBUILD)

### Enabling services

* systemd.preset - Service enablement presets
* [man 5 systemd.preset](https://www.systutorials.com/docs/linux/man/5-systemd.preset/)

**Note**: the preset name shall start with a two-digit number < 99.

```shell
install -Dm0644 systemd.preset "$pkgdir"/usr/lib/systemd/system-preset/20-"$pkgname".preset
```

Example package: 
* [pkg/de-p1st-networkmanager/systemd.preset](pkg/de-p1st-networkmanager/systemd.preset)
* [pkg/de-p1st-networkmanager/PKGBUILD](pkg/de-p1st-networkmanager/PKGBUILD)

### Multiple providers

Example:
* Two packages (`de-p1st-test2` and `de-p1st-test3`) provide `de-p1st-test`
* If one installs `de-p1st-test` he can interactively choose one which provider to select:

```
$ sudo pacman -S de-p1st-test
:: There are 2 providers available for de-p1st-test:
:: Repository de-p1st
   1) de-p1st-test2  2) de-p1st-test3

Enter a number (default=1): 
```

---

**TODO**:
* How does Pacman pick the default option? Are packages simply
ordered alphabetically?
* de-p1st-pacman -> ungoogled-chromium
  * https://github.com/ungoogled-software/ungoogled-chromium-archlinux#open-build-service-repository
* for each PKG: built with docker then sign wit pgp
