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!

FreeBSD Foundationals: rc.d - The Service Framework That Fits in Your Head

The fourth in the FreeBSD Foundationals series. This one picks up where the boot article stopped, at the moment init runs /etc/rc. It covers how rc finds and orders scripts with rcorder, how rc.conf and its layers are really just shell, what rc.subr gives you for free, how to drive it all with service and sysrc (including inside jails), how to write a correct rc.d script for your own daemon using daemon(8) supervision, and the pidfile trap that makes “service stop” restart your process instead of stopping it. Then an honest audit of the rc.d scripts running my own Mastodon, Zigbee2MQTT and NetBox jails. Plus service jails, debugging, and an honest comparison with systemd units.
