# Serial Pi
Download and extract Fedora Minimal image:
```sh
curl -fLO 'https://dl.fedoraproject.org/pub/fedora-secondary/releases/39/Spins/aarch64/images/Fedora-Minimal-39-1.5.aarch64.raw.xz'
unxz Fedora-Minimal-39-1.5.aarch64.raw.xz
```
Resize the disk to match the SD card:
```sh
truncate -s $((31291392 * 512)) serialpi.img
virt-resize --expand /dev/sda3 --no-expand-content Fedora-Minimal-39-1.5.aarch64.raw serialpi.img
```
The `--no-expand-content` argument is necessary because otherwise,
`virt-resize` fails with an error, as the ext4 filesystem in the image uses
features it does not support.
Populate `authorized_keys`:
```sh
cp ~/.ssh/id_ed25519_sk.pub authorized_keys
```
Customize with `guestfish`:
```sh
guestfish -a serialpi.img -f customize.guestfish
```
Write image to SD card:
```sh
pv serialpi.img | dd of=/dev/disk/by-id/usb-Generic_STORAGE_DEVICE_000000001206-0:0 bs=1M oflag=sync conv=sparse
```
