Hi, since 2.50 portage supports the configfiles /etc/portage/package.{mask,unmask,keywords,use} but not /etc/portage/package.features This would permit to ie. use ccache only for a few packages which i often recompile, like cvs-versions. So cchache would stay fast because the cache is small and contains only what you want to...
FEATURES should only be global settings. Try /etc/portage/bashrc
