That's a semantic issue. It works as designed in that setting an option in src.conf does set the specified flags for make in /usr/src. Unfortunately some of the options were added as options, but the code to actually make the option effective was not. The more popular options work fine...SENDMAIL, BIND, BSNMP, and many more. Most of those that are simple skips of doing a make on a given directory are fine, too. In fact, most are working as expected. The problems are with more complex options that get involved with complex library dependencies. WITHOUT_SSH was broken for quite a while due to interactions with several other options. (Just look through the Makefiles involved in ssh and the complexity of the other cryto-related tools. It's not trivial and there are way too many options to fully test all possible combinations. (As far as I can tell, SSH issues are now resolved.) I will also point out that several options DO state that they have no effect in the man page, but that assumes people actually read the text associated with a given option. -- R.
