sudo arkdep-build customlinux
# Or alternatively using a custom image name
sudo ARKDEP_OVERWRITE_RANDOM='customlinux_v1.0' arkdep-build customlinux
sudo ARKDEP_CUSTOM_NAME='customlinux_v1.0' arkdep-build customlinux
```
Once done you can find compressed and uncompressed copies of your new image in the `target` directory.
arkdep will by default generate a psuedo-random hex string and use this as the name of your image. This behaviour can be overwritten by assigning a custom name to the `ARKDEP_OVERWRITE_RANDOM` environment variable.
