I finally dove into the world of Immutable/Atomic Linux Desktops. Universal Blue (Aurora/Bazzite) is doing for the desktop what CoreOS did for servers. My analysis of the stack (OSTree, bootc) and why I think this is the future: blog.hofstede.it/immutable-linu… #linux #tech

I’ve documented the clean, native way to join FreeBSD 15 to a FreeIPA realm. Pure Kerberos (GSSAPI). Lightweight LDAP (nslcd). No local user management Keep your base system sane. blog.hofstede.it/integrating-fr… #FreeBSD #SysAdmin #FreeIPA #OpenSource

New blog post: I wrote an Ansible connection plugin for FreeBSD jails. Manage jails without SSH inside each one - connects to the host and uses jexec, just like you would manually. blog.hofstede.it/managing-freeb… #freebsd #ansible #automation #devops

New post: AI-assisted Linux troubleshooting with linux-mcp-server Your AI can now directly query system info, services, logs & network state instead of you copy-pasting outputs back and forth. blog.hofstede.it/interactive-sy… #Linux #AI #MCP #RHEL #Fedora #SysAdmin #OpenSource

New post: Self-hosting a static blog on FreeBSD 15.0 with Bastille, Caddy, PF, and CI/CD deployment. Covers the full stack, from jail isolation to restricted rsync. Simpler than containers. blog.hofstede.it/hosting-a-stat… #freebsd #devops #blog

FreeBSD + BastilleBSD + Mastodon = ❤️ I wrote about running burningboard.net in a fully dual‑stack, multi‑jail FreeBSD deployment. Clean design, central PF firewall, zero Docker. blog.hofstede.it/migrating-burn… #freebsd #mastodon #jails #bastillebsd #pf

If you want to build production level container deployment without @kubernetesio, Quadlets might be the answer! Checkout this blog from Christian Hofstede-Kuhn: blog.hofstede.it/production-gra… #podman #opensource
