A Pi 3B+ (stickah.local) shares a Phomemo PM246 to the LAN as a plain CUPS queue, so any machine can print 4x6 labels -- fulfillr-site's shipping labels in particular -- without installing the vendor driver, which is x86-64 only. The role builds the TSPL CUPS driver from source instead. It is Debian, not Fedora, so it lives in its own inventory and playbook (make deploy-labelprint / check-labelprint) and the home.debyl.io roles can never run against it. make bootfs renders its cloud-init first-boot files onto a freshly imaged SD card from the same templates the role uses. The Wi-Fi credentials for the home and rescue networks are in the vault. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
