Ah, that explains it. So it's entirely possible then that rebooting my system with it rw caused such catastrophic failure on my empeg?

I need to fiddle with rsync some more as it's very sensitive to things being rw or ro. It seems to be that specifying a log and/or pid file in rsyncd.conf prevents it starting when ro, but even without that, rsync can prevent the ro operation succeeding - keeping a file open maybe?

So is it OK to sync with the player app still running?

What about a nice graphic while syncing? Is it even possible to do this from the command line?
