Gabriel Guillou

👨‍💻 About Me

I'm Gabriel Guillou, a Linux systems administrator focused on virtualisation, operations and automation.

I build and maintain DaemonCores, a solo project that brings the bootc/OSTree immutable model to Debian: signed OCI system images, Debian packages, Secure Boot, and a CI that boot-tests every image before publishing it.

  • 2025 - 2026 - Systems Administrator (volunteer) - Wilink-Info: Proxmox server setup, automated deployments, monitoring
  • 2024 - 2025 - ERP Developer (work-study) - Hutchinson: AS/400 to Linux migration, internal tooling, Linux automation

🎯 Degrees

  • 2025 - General Computer Science Bachelor's Degree
  • 2024 - BTS SIO - SLAM option (software development)
  • 2022 - Vocational Baccalaureate in Digital Systems - Networks and telecommunications option

🚀 Featured Projects

  • debian-bootc - Debian 13 as a bootc/OSTree image: bootc stack packaged for Debian, BLS GRUB signed for Secure Boot, online/offline installer ISOs
  • DaemonCores-VE - Proxmox VE as a transactional image, with a Proxmox storage plugin running OCI images as immutable LXC containers and a Docker Compose to Podman/Quadlet converter
  • DaemonCores-CI - Reusable GitHub Actions pipeline: amd64/arm64 builds, signed APT repositories, QEMU/KVM boot tests before publication
  • DaemonCores-Phone - R&D: Debian/bootc base for smartphones and device descriptor schema
