To bad there's not a way to do this without /usr/src. If you just extract this new system over your current system, how does that get rid of things you removed? For example I got rid of bluetooth and various other things that I don't want installed. Thanks, Also you can save space by not keeping /usr/ports and installing binary packages. If custom options are need you will have to run own package repo using poudriere. 1. http://termbin.com/ad1c 2. http://termbin.com/rvd8 _______________________________________________ freebsd-questions@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" -- Take Care, Tyler Littlefield Tyler Littlefield Consulting: website development and business solutions. <http://tylerlittlefield.me>; My personal site <http://tysdomain.com>; My Linkedin <https://www.linkedin.com/in/ty-lerlittlefield>; @Sorressean on Twitter <http://twitter.com/sorressean>;
