- New build-iso-workstation.sh / autoinstall/user-data-workstation: writes the workstation tier marker (/opt/cezen/tier), reuses the Server S (starter) hardware profile and Ansible playbook under the hood - firstboot-setup.sh: additive WORKSTATION_MODE branch (gated on CEZEN_TIER=workstation) skips the Server tier-selection menu entirely — Workstation is never offered as a Server S/M/L/Max choice. Non-workstation installs are unaffected. Also relabels the Server tier menu to Server S/M/L/Max, matching the earlier portal rename - install.sh and the Ansible playbooks are unchanged; only the pre/post marker files differ between a Server S and Workstation install - README.md + MIGRATION_NOTES.md updated with the new build path and what is still manual (CEZEN_TIER isn't yet templated into the deployed cezen-api systemd unit — tracked as follow-up)

# Nexus One AI — Workstation ISO Builder
|
|
# Hardware target: personal AI appliance (NVIDIA DGX Spark, RTX 5090
|
|
# Workstation, or RTX PRO 6000 Workstation; 64 GB RAM, 2 TB NVMe)
|
|
#
|
|
# Nexus One AI Workstation is a standalone product category (see
|
|
# ../README.md → "Product Structure"), not a Server tier. This build
|
|
# shares the Server S ("starter") hardware profile and Ansible playbook
|
|
# under the hood, but writes a distinct "workstation" tier marker so the
|
|
# installed system identifies and brands itself as Nexus One AI
|
|
# Workstation rather than a Server S install.
|
|
#
|
|
# Usage:
|
|
# cd ~/aipackage
|
|
# bash autoinstall/build-iso-workstation.sh
|
|
#
|
|
# Output: autoinstall/cezen-ai-workstation-ubuntu2204.iso
|
|
# Flash to USB:
|
|
# diskutil unmountDisk /dev/diskN

# sudo dd if=cezen-ai-workstation-ubuntu2204.iso of=/dev/diskN bs=4m status=progress
