Himmelblau reports VERSION_ID from /etc/os-release as the device OS version, so Intune showed "44". Give himmelblaud and himmelblaud-tasks their own os-release (bind-mounted in their mount namespace only) with VERSION_ID set to OSTREE_VERSION, e.g. 44.20261019.0. The rest of the system keeps the stock VERSION_ID that toolbox, flatpak and dnf expect. Add an Intune custom compliance discovery script and rules for Microsoft Defender for Endpoint (installed, running, onboarded, licensed, healthy, real-time protection, definitions up to date). These are uploaded to Intune, not shipped in the image. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
