## Aegis
`aegis` is a Raspberry Pi 4 running Fedora CoreOS. Provision it once with
`ansible/bootstrap/aegis.bu`, after replacing the SSH public-key placeholders:

```bash
butane --strict --pretty --output aegis.ign ansible/bootstrap/aegis.bu
```
The bootstrap reserves partition 5 on `/dev/mmcblk0` for `/var/lib`. On the first boot it
generates a random LUKS2 key, enrolls it in the attached TPM2 device, and formats the unlocked
volume as btrfs. This is destructive for that partition and requires a TPM2 module/device; a
Raspberry Pi 4 has no TPM onboard. The `core` and `pi` users both receive the configured SSH key.
The `core` and `pi` users both receive the configured SSH key.
The controller then manages it remotely as `core@aegis`; unlike local desktop profiles, Aegis is
intentionally an SSH inventory target. `profile_aegis` manages rootful Podman Quadlets for AdGuard
