## Build the airgap-boot disk image:

```bash

$ nix build .#nixosConfigurations.airgap-boot.config.system.build.isoImage

```

## Test the airgap-boot image:

```bash

qemu-run-iso

```

## Test the airgap-boot image with a host passed device:

```bash

# Find the device of interest, in this case a thumbdrive:

❯ lsusb | grep -i sandisk

Bus 001 Device 030: ID 0781:5567 SanDisk Corp. Cruzer Blade

# Pass the device to qemu based on vendor and product id:

sudo qemu-run-iso -device nec-usb-xhci,id=xhci -device usb-host,vendorid=0x0781,productid=0x5567

# Or, pass a bus and address to qemu:

sudo qemu-run-iso -device nec-usb-xhci,id=xhci -device usb-host,hostbus=1,hostaddr=30

```

## Fomat the airgap-data device:

WARNING -- BE ABSOLUTELY SURE YOU HAVE THE CORRECT DEVICE LISTED AS THIS DRIVE WILL BE WIPED!

WARNING -- Do a dry first and review the output script if desired.

WARNING -- The device should be at least 16 GB in size or the format may fail.

Below, `$YOUR_AIRGAP_DATA_DRIVE` is the path to the airgap data device,

which may be something like: `/dev/sdb`.

### From within the airgap boot image:

```bash

format-airgap-data --dry-run --argstr device "$YOUR_AIRGAP_DATA_DRIVE"

# If satisfied with the dry run script, proceed with the formatting:

format-airgap-data --argstr device "$YOUR_AIRGAP_DATA_DRIVE"

```

### From the flake devShell of a networked machine:

```bash

disko -m disko --dry-run -f .#airgap-data --argstr device "$YOUR_AIRGAP_DATA_DRIVE"

# If satisfied with the dry run script, proceed with the formatting:

sudo disko -m disko -f .#airgap-data --argstr device "$YOUR_AIRGAP_DATA_DRIVE"

```
