So you run set FEATURES=test to run a package's test suite during keywording. Later, you emerge -vuNDa ... and portage wants to reemerge that package with USE=-test.
Can't we avoid this somehow? I presume in the vast majority of cases emerging with FEATURES/USE=test doesn't actually affect what's installed. I'd guess we'd need to be able to remove 'test' from the set of IUSE and have a new helper function to check if 'test' is in FEATURES? Matt
