Mastodon

Welcome to Larvitz Blog! I’m Christian, a Senior Consultant by day and FreeBSD enthusiast by night, with over 20 years in enterprise IT. Here I write about FreeBSD jails, PF firewalling, self-hosting, Linux system administration, and anything that’s cleanly engineered. Most articles are hands-on guides born from running my own infrastructure, from dual-stack networking and Ansible automation to hosting a Mastodon instance on FreeBSD.

Have a question or want to discuss something? Find me on the Fediverse at @Larvitz@burningboard.net. I’m always happy to chat!

No Proxmox Backup Client for RHEL? Hold My Container Runtime

RHEL 10 on ARM64, a Proxmox Backup Server, and no convenient native client package. I borrowed the client from an old server container, mounted the host root filesystem read-only, and gave SELinux a very specific explanation. Five minutes later, I had an encrypted, incremental backup. There are caveats. Updated 2026-10-18 with a maintained client image for x86_64 and aarch64 on ghcr.io.
