Mastodon

Welcome to Larvitz Blog! I’m Christian, a Cloud 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.

The source is not public, but the design is worth documenting.

chana_masala.sh: A Recipe as a Shell Script

Some years ago a chana masala arrived in a HelloFresh box and never left the household again. It has since been refactored, hardened, and put under version control. Here is the current release: a chickpea curry for hungry IT people, documented the only way I know how - as a bash script with a proper runbook attached.
