adapting src.conf to nanobsd CONF build options

[Dimitar Vassilev]

Hello all,
I'd like to implement the following src.conf for nanobsd. Goal is to
have these subset neither being built, nor installed.

cat /etc/src.conf

WITHOUT_BLUETOOTH
WITHOUT_CALENDAR
WITHOUT_CPP
WITHOUT_CTM
WITHOUT_CVS
WITHOUT_CXX
WITHOUT_DICT
WITHOUT_EXAMPLES
WITHOUT_FLOPPY
WITHOUT_GAMES
WITHOUT_GCOV
WITHOUT_IPFILTER
WITHOUT_INFO
WITHOUT_INSTALLLIB
WITHOUT_IPFW
WITHOUT_IPX
WITHOUT_LPR
WITHOUT_MAKE
WITHOUT_GROFF
WITHOUT_NCP
WITHOUT_NIS
WITHOUT_FREEBSD_UPDATE
WITHOUT_RCS
WITHOUT_SHAREDOCS

As far as I have read, what I need to do is put these into
CONF_BUILD section to prevent buildworld compiling them
Do I need to put them also into CONF_INSTALL and CONF_WORLD to prevent
them from being propagated into the image
or just having them into CONF_BUILD will suffice?
Thanks,
Dimitar
