# Offline Installer (BYODE)
|
||
|
|
|
||
|
|
The offline installer (`/usr/local/bin/antergos-offline-install`) is a bare-minimum installer for situations where the Calamares online installer can't work — no internet, or you want a minimal base to build on. It is **experimental** and best-effort; the Calamares online installer remains the primary path.
|
||
|
|
|
||
|
|
The script is adapted from Valve's SteamOS `repair_device.sh` (the Zenity prompt and pretty-output helpers are lifted straight from there).
|
||
|
|
|
||
|
|
## What it does
|
||
|
|
|
||
|
|
1. Verifies it's running as root in a live Antergos NeXT session (checks for `/run/artix/bootmnt/LiveOS/rootfs.img`)
|
||
|
|
2. Warns that it installs **no desktop environment** — just the base system
|
||
|
|
3. Lets you pick a target disk via `lsblk` + Zenity, then partitions it:
|
||
|
|
- GPT table
|
||
|
|
- 512 MiB EFI partition
|
||
|
|
- 300 MiB swap
|
||
|
|
- Root partition filling the rest
|
||
|
|
4. Formats: `vfat` (ESP), `swap`, `btrfs` root
|
||
|
|
5. Creates btrfs subvolumes: `@`, `@home`, `@cache`, `@log`, `@snapshots`
|
||
|
|
6. Extracts the live rootfs (squashfs) to the target
|
||
|
|
7. Generates an fstab with `subvol=` mounts and `compress=zstd`
|
||
|
|
8. Chroots in: runs `mkinitcpio -P`, installs GRUB as `Antergos`, sets hostname
|
||
|
|
9. Prompts for a root password and a daily user (added to `wheel` + sudoers)
|
||
|
|
10. Enables services via `artix-service`: NetworkManager, dbus, acpid, bluetoothd, cronie, cupsd, dhcpcd, power-profiles-daemon, syslog-ng, userspawn
|
||
|
|
11. Configures **snapper** for automatic snapshots (6 hourly + 7 daily + 4 weekly, via cron jobs)
|
||
|
|
12. Unmounts, syncs, and offers to reboot
|
||
|
|
|
||
|
|
## After first boot
|
||
|
|
|
||
|
|
Since no desktop environment was installed, connect to the internet and run:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo pacman -Sy plasma-meta
|
||
|
|
```
|
||
|
|
|
||
|
|
or install any other DE you want.
|
||
|
|
|
||
|
|
## Caveats
|
||
|
|
|
||
|
|
- **Destroys all data** on the selected disk — confirmed via Zenity twice.
|
||
|
|
- No Calamares integration (no partitioner UI, no locale/keyboard/user pages).
|
||
|
|
- Package lists are baked into the live squashfs; there is no post-install package installation step, so the system matches the ISO's rootfs as of build time.
|
||
|
|
- Bootloader is GRUB only — no systemd-boot, no rEFInd.
|
||
|
|
- Still needs internet on first boot for anything beyond the base.
