For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook: 8 --- 12 unchanged lines hidden (view full) --- 21 includes various WITNESS- related kernel options, INVARIANTS, malloc 22 debugging flags in userland, and various verbose features in the 23 kernel. Many developers choose to disable these features on build 24 machines to maximize performance. (To completely disable malloc 25 debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely 26 disable the most expensive debugging functionality run 27 "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 28 | 1 Updating Information for FreeBSD current users. 2 3This file is maintained and copyrighted by M.

Please try this 2006 approach if you encounter problems with a major version upgrade. Since 2007 the stable 4.x branch point, one has generally been able to upgrade from 2008 anywhere in the most recent stable branch to head / current (or even the 2009 last couple of stable branches).
