# Building the ISO
|
|
|
|
The ISO is built with `buildiso` (from Artix `artools` package) plus a customized profile. You need an **Artix-based** system to build.
|
|
|
|
## Prerequisites
|
|
|
|
```bash
|
|
pacman -S artools squashfs-tools
|
|
modprobe loop
|
|
```
|
|
|
|
`squashfs-tools` is needed for `mksquashfs`. The `loop` module must be loaded for `mount -o loop` during image assembly.
|
|
|
|
## Clone and configure
|
|
|
|
```bash
|
|
git clone https://github.com/Antergos-NeXT/antergos-iso.git
|
|
cd antergos-iso
|
|
|
|
export WORKSPACE_DIR="$PWD"
|
|
|
|
# Override pacman config with our repo (antergos-pkgs)
|
|
mkdir -p ~/.config/artools/pacman.conf.d
|
|
cp pacman.conf.d/iso-x86_64.conf ~/.config/artools/pacman.conf.d/
|
|
```
|
|
|
|
Without this override, `buildiso` uses `/usr/share/artools/pacman.conf.d/iso-x86_64.conf` (from the artools package), which lacks the `[antergos-pkgs]` repository. The build will then try to fetch our custom packages (branding, Calamares config, wallpapers) from Artix repos and fail.
|
|
|
|
## Build
|
|
|
|
```bash
|
|
sudo -E ./buildiso -p antergos
|
|
```
|
|
|
|
- **Use `./buildiso`**, not `buildiso`. The system `/usr/bin/buildiso` lacks `--overwrite='*'`, which causes file conflicts between `calamares` and `calamares-branding-antergos-next` (both claim `/usr/share/calamares/branding/default/`). Our repo's `./buildiso` has it.
|
|
- **`sudo -E`** is required. Without `-E`, `WORKSPACE_DIR` is stripped and `load_profile()` returns empty `HAS_LIVE`/`LIVEUSER`, causing the build to fail early.
|
|
|
|
## Output
|
|
|
|
The ISO appears in `/var/lib/artools/buildiso/iso/antergos/`:
|
|
|
|
```
|
|
/var/lib/artools/buildiso/iso/antergos/
|
|
├── antergos-<date>.iso # Bootable ISO
|
|
└── antergos-<date>.sha1sum # Checksum
|
|
```
|
|
|
|
First build pulls ~5 GB from the internet (package downloads). Subsequent builds use pacman cache.
|
|
|
|
## Environment variables
|
|
|
|
| Variable | Purpose |
|
|
|----------|---------|
|
|
| `WORKSPACE_DIR` | Must point to repo root. `buildiso` looks for profiles under `$WORKSPACE_DIR/iso-profiles/` |
|
|
| `COMPRESSION` | Squashfs compression type (e.g. `zstd`, `gzip`, `xz`). If unset, `mksquashfs` produces a zero-size sparse file instead of a valid squashfs |
|
|
|
|
## Troubleshooting
|
|
|
|
### "File conflict" errors during build
|
|
|
|
This means `--overwrite='*'` is not being passed to `basestrap`. Make sure you're using the repo's `./buildiso`, not the system one:
|
|
|
|
```bash
|
|
# Wrong — system buildiso without --overwrite:
|
|
buildiso -p antergos
|
|
|
|
# Correct:
|
|
./buildiso -p antergos
|
|
```
|
|
|
|
### Build fails with "HAS_LIVE is empty"
|
|
|
|
Forgetting `sudo -E`:
|
|
|
|
```bash
|
|
# Wrong — WORKSPACE_DIR not preserved:
|
|
sudo ./buildiso -p antergos
|
|
|
|
# Correct:
|
|
sudo -E ./buildiso -p antergos
|
|
```
|
|
|
|
### buildiso can't find our custom repo
|
|
|
|
The pacman config override is missing:
|
|
|
|
```bash
|
|
mkdir -p ~/.config/artools/pacman.conf.d
|
|
cp pacman.conf.d/iso-x86_64.conf ~/.config/artools/pacman.conf.d/
|
|
```
|
|
|
|
### Zero-size squashfs (ISO exists but is tiny)
|
|
|
|
`$COMPRESSION` is unset. Either set it in `profile.yaml` or pass it via environment:
|
|
|
|
```bash
|
|
export COMPRESSION=zstd
|
|
sudo -E ./buildiso -p antergos
|
|
```
|
|
|
|
Remove the stale image before retrying:
|
|
|
|
```bash
|
|
rm -rf /var/lib/artools/buildiso/iso/antergos/
|
|
```
|
|
|
|
### Corrupted pacman cache
|
|
|
|
If `basestrap` fails with checksum errors, clear the cache:
|
|
|
|
```bash
|
|
rm -rf /var/lib/artools/buildiso/pkg/antergos/cache/
|
|
```
|
|
|
|
Then rebuild.
|
|
|
|
## CI builds
|
|
|
|
The CI pipeline (`.github/workflows/build.yml`) handles all of the above automatically. It runs in an Artix container, sets `WORKSPACE_DIR`, overrides pacman config, mounts a 12 GB tmpfs, and builds the ISO. It also runs the AI community moderator on issues/PRs (`.github/workflows/ai-moderator.yml`).
|
|
|
|
An Internet Archive upload step exists in the workflow but is **currently disabled** (`if: false`) — builds are manually verified first. When enabled it uploads with identifier `antergos-next-YYYYMMDD-<run_number>`.
|
|
|
|
Trigger CI manually from the GitHub Actions tab (push trigger is disabled).
|
|
|
|
## Local pacman repo
|
|
|
|
To use the custom packages repo on an installed system:
|
|
|
|
```ini
|
|
[antergos-pkgs]
|
|
SigLevel = Optional TrustAll
|
|
Server = https://antergos-next.github.io/antergos-packages
|
|
```
