as admin on the NAS:

1. cd $( getcfg Nomad Install_Path -f /etc/config/qpkg.conf )
2. nomad acl bootstrap and record output
3. ensure working: NOMAD_TOKEN=<Secret ID> nomad node status -self
4. generate token for init script: NOMAD_TOKEN=<Secret ID> ./generate-init-script-token.sh
5. ensure working: NOMAD_TOKEN=$( cat startup-shutdown-token ) nomad node status -self
