FreeBSD user Frederic Cambus put together a cheat sheet on how to bootstrap a FreeBSD workstation and keep it up to date.

System configuration

Setting the timezone

cp /usr/share/zoneinfo/Europe/Warsaw /etc/localtime

Setting an alternative keymap in console

The keymap directive should be set in rc.conf :

keymap="fr.iso.acc"

Performing binary updates for the base system

freebsd-update fetch
freebsd-update install
