If you don't want it exposed to users, then use a USE_EXPAND variable. Like zmedico said in EAPI 3 a normal use flag could be hidden but probably better to not have to migrate everything with prefix support to EAPI 3. Out of the existing USE_EXPAND variables USERLAND makes most sense to me but we could also introduce a new one too. Regards, Petteri
