Yes — you can absolutely do most of this inside a **Debian-based container** (or even on Linux Mint, which is Ubuntu-based), with some caveats:
|

|
### 1️⃣ What works in a container
|
|||
|
|
|
|||
|
|
* **Debootstrap / building the ISO filesystem** – you can create the `chroot` and populate it inside a Debian container.
|
|||
|
|
* **Copying your tools** (`asl-auth-host`, `asl-rescue`, helpers) into the ISO root.
|
|||
|
|
* **Overlay scripts and directory structure** – fully container-compatible.
|
|||
|
|
* **Generating the ISO** using `genisoimage` or `xorriso` – works fine in a container.
|
|||
|
|

|
### 2️⃣ What **won’t fully work** in a container
|
|||
|
|
|
|||
|
|
* **ZFS pool creation** (`zpool create`) – you need **kernel support** for ZFS, and containers usually don’t have full access to `/dev` to create loopback-backed pools.
|
|||
|
|
|
|||
|
|
* Workarounds:
|
|||
|
|
|
|||
|
|
* Use a **loopback file inside the container** and mount ZFS on the host after building.
|
|||
|
|
* Or skip actual pool creation, just **pre-create the dataset folder structure**, and mount ZFS later on the real machine.
|
|||
|
|
|
|||
|
|
* **Boot testing** – you can build the ISO in a container, but to actually boot and test, you’ll need a VM or real hardware.

### 3️⃣ Suggested container workflow
|

```text
|
|||
|
|
[Host Linux Mint]
|
|||
|
|
|
|
|||
|
|
v
|
|||
|
|
[Debian container] --> run build_asl_auth_host_iso.sh
|
|||
|
|
|
|
|||
|
|
v
|
|||
|
|
[Output ISO] --> copy to VM or USB to test boot
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Steps:
|
|||
|
|
|
|||
|
|
1. Run a Debian container:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
docker run -it --name asl-build -v $PWD/work:/work debian:bullseye bash
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
2. Inside the container, install required packages:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
apt update
|
|||
|
|
apt install -y debootstrap genisoimage squashfs-tools xorriso
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
3. Copy your scripts and binaries into the container (`/work` folder).
|
|||
|
|
|
|||
|
|
4. Run the ISO build script (`build_asl_auth_host_iso.sh`).
|
|||
|
|
|
|||
|
|
5. Copy the generated ISO back to your host for boot testing.
|
|||
|

|
✅ **Bottom line:**
|
|||
|
|
|
|||
|
|
* You **can** build the ISO entirely in a container.
|
|||
|
|
* For **ZFS pools or boot testing**, you need either host privileges or a VM for full functionality.
|
|||
|
|
* On Linux Mint, the container approach keeps your host clean and reproducible.

|||

|
|
|||
|
|
If you want, I can **rewrite the build script specifically for container-friendly execution**, skipping ZFS creation but keeping the dataset folders so it’s ready to mount ZFS later. This is the smoothest workflow for Linux Mint.
|
|||

|
|
|||
|
|
Do you want me to do that?
