# README
## Rocky Linux 9 generic ARM64/Aarch64 images
### Extracting the image
You probably downloaded the `Rocky-9-aarch64-minimal-YYYY.MM.DD-HHMMSS.raw.zst` file and are wondering how to extract. Run the following command:
```bash
zst --decompress Rocky-9-aarch64-minimal-YYYY.MM.DD-HHMMSS.raw.zst
```
### Flashing the image
```bash
# flash the extracted image
dd if=Rocky-9-aarch64-minimal-YYYY.MM.DD-HHMMSS.raw of=<device> bs=4M conv=sync status=progress
# flash without extracting the '.zst' file
zstdcat Rocky-9-aarch64-minimal-YYYY.MM.DD-HHMMSS.raw.zst | dd bs=4M conv=sync status=progress of=<device>
```
### SSH
SSH is enabled on port `22`. Logging-in as **`root` is disabled**, but you can login as user `rocky`.
### User credentials
```
username: rocky
password: rockylinux (you will be forced to change this)
```
```
username: root
password: <disabled>
```
### Expanding the rootfs
`sudo /usr/local/bin/expand-rootfs.sh`
## PSA for non-Rocky folks
There are two repositories that are maintained by Rocky Linux. One repository provides packages that are specific to SIG/AltArch for SBC enablement. Another repository is basically ELRepo + some Rocky stuff. Depending on your needs, this may or may not be a good thing. Please act accordingly.
## Notes for executing the script
Firstly, the prerequisite for running all the commands in the `create-image.sh` script can be installed with the following command:
```bash
# enable EPEL first, because `appliance-tools` is from EPEL
dnf install appliance-tools perl-Digest-SHA zstd
```
