Ok, I can find two different problems wrt udisks and its testsuite. First is that it tests the INSTALLED udisks. If you do not have udisks installed it skips all tests. Second is that "make check" launches "sudo" if you run it with FEATURES="userpriv". I also think it does some device mockery. So my question is if the testcase is worth having enabled, and in that case if we should poke upstream to do more nice stuff.
nod, it doesn't make sense to run this testsuite from ebuild at all. restricted.
