I "cloned" my head slice (4) to slice 3, updating source on slice 3 to r313995, rebooted to slice 3... and noticed that it didn't seem slugglish at all (unlike the earlier "smoke-test"). So before I did anything else, I rebooted it... and the countdown after "Syncing disks, vnodes remaining..." was about 1 second each..... So I'm not sure what happened, but it looks as if I can't (readily) reproduce the symptom. I'll try experimenting a bit more as time permits today (but I actually use the laptop in my day-to-day work, so that may prove challenging). Sorry for the noise. Peace, david --=20 David H.
