A further consideration in the source code-related sections is that building 
your own {world, kernel} will bump you off the support path for binary updates 
and upgrades with freebsd-update.  This is increasingly a consideration for 
our default kernel configuration: kernel options that require recompilation 
force users not to use the most user-friendly upgrade path we have.
