# Packer for Debian based GNS3 appliances

## Packer Version Dependency

Packer versions 1.6.0 or later do not accept templates
that use the `iso_checksum_type` attribute.
To use these newer versions, you must delete the line
containing `iso_checksum_type` from debian.json.

printf "instance-id: debian\nlocal-hostname: debian\n" > meta-data
mkisofs -output debian-cloud-init-data.iso -volid cidata -joliet -rock user-data meta-data
```
