Or is Logan hunting down everything anyway? I'm not hunting down everything. There's too much brokenness. I've done a bunch of work: there's that series plus an mdadm branch I'll send to the list later (just linked it on my previous email). But even after all that, I still have ~25 broken tests, but I've marked those tests and they shouldn't stop the test script from running everything. Logan
