# Podman Quadlet: Base

## Overview

The base cookbook provides foundational configuration for Fedora CoreOS systems. It includes:

- **fastfetch**: A system information tool displayed on login, with color-coded output (red for root, blue for regular users).
- **tmpfiles configuration**: Sets up required directories such as `/var/lib/virtiofs/data`.
- **QEMU guest agent**: Optional installation for better VM integration.
- **SSH key persistence**: Backs up and restores SSH host keys across reboots.
- **resolv.conf resync**: Keeps `Network=host` containers in sync with the host's DNS.
  With `Network=host`, Podman snapshots `/etc/resolv.conf` at container creation and bind-mounts
  the copy, so a later DNS change (e.g. a DHCP renewal) never reaches running containers. A
  `systemd.path` unit watches `/etc/resolv.conf` and a oneshot service rewrites each host-network
  container's snapshot **in place** (same inode, no restart); bridged containers are left untouched.
  See [issue #1](https://github.com/nmasse-itix/podman-quadlet-cookbook/issues/1).

This cookbook is used as an implicit dependency for other cookbooks that run on Fedora CoreOS.

## Usage

In a separate terminal, follow the logs.

```sh
sudo make tail-logs
```

Install the base configuration.

```sh
sudo make clean install
```

You should see the **install-fastfetch.service** downloading and installing fastfetch.
On next login, fastfetch will display system information.

To verify the installation:

```sh
fastfetch --version
```

Finally, remove the configuration and its data.

```sh
sudo make uninstall clean
```
