@stefano on a complety different topic, Time Capsule was based on netbsd(if I remember well). It saved my life, but wasn’t great hardware-wise (mine was dead, I guess that was a dc conversion pb, but never tried to fix the board), and the old sharing technology AFP was not great for over the wlan mounts. The same (dedicated hw with zfs and smb) would rock nowadays.
Oh wait, an Italian guy did write somethin’ on the topic…
true info: I would love apple to get back in the timecaspule/airport technology, simplicity-wise it was great. At this time user experience was the core of Apple. I miss these days.
