Then you use the custom pkg url to update your other machines. Quick primer on poudriere: https://www.freebsd.org/doc/handbook/ports-poudriere.html Digital Ocean did a write up on exactly what you're requesting here: https://www.digitalocean.com/community/tutorials/how-to-set-up-a-poudriere-= build-system-to-create-packages-for-your-freebsd-servers Best, Owen
