Mmm, I just tried updating my machine and it's been stuck at "Performing
incremental rsync." for at least 20 minutes now. Someone had mentioned that
the first person to access an update triggers some sort of procedure on the
server but I wouldn't expect it to take that long. (And yes, I had
disabled Automatic Power Management before starting the update.)

What also seems odd is that even though Sugar's battery monitor still shows
65% the power LED turned red during the update process. Now that I've
connected the AC adapter the power LED is indeed orange but the tray icon
still acts as though I'm running on batteries.
