In the section on setting up /etc/make.conf instructions are given to put a CHOST line in, and to make sure it's correct. (Associated with this, the make.conf supplied as default in the stage3 download has a default CHOST line.) It turns out that these days CHOST is defined in /etc/make.profile; specifically the profile to which that is a symlink. Therefore the CHOST line in /etc/make.conf is unnecessary, as is the documentation about it. The references to CHOST should be removed from both the handbook and the stage3 default /etc/make.conf; or at least have a mention that you can put it in if for some mad reason you need to override the profile's CHOST. Though /etc/make.conf.example is probably the place for that. The current documentation doesn't *fail* in that the resulting system works; it's just unnecessary duplication (and might be more failure-prone as it may encourage some to fiddle with it when they shouldn't!) Reproducible: Always
that's not really true. there will always be a case for setting the CHOST in make.conf as it is impossible to have profiles for every possible CHOST variant.
Will leave as-is per comment #1. Thanks for the suggestion, though.
