[Late to the topic, but two devs have asked me on IRC that I should post this, in order to have it documented as part of the thread.] I see no point in discouraging IUSE defaults, given that they are purely advisory for the package manager: "[...] any use flag name in IUSE may be prefixed by at most one of a plus or a minus sign. If such a prefix is present, the package manager may use it as a suggestion as to the default value of the use flag if no other configuration overrides it." [1] Portage can be made to ignore IUSE defaults by omitting "pkginternal" from USE_ORDER, i.e. by adding the following line to make.conf [2]: #USE_ORDER="env:pkg:conf:defaults:pkginternal:repo:env.d" USE_ORDER="env:pkg:conf:defaults:repo:env.d" One could even think about adding this to a future minimal profile.
