I tried to get this working once on a liveCD I was making quite a while ago, never had any luck with it though. It looks like it has improved since then.

One thing that the CD-Persistant module is supposed to be capable of that is not listed in Puppy's description of their CD is it's CD-RW functionality. With a morphix CD-RW and CD-Persistant, the track storing your /home directory can be wiped out and recreated so that it is even more like just using your hard drive. The downside of this is a much larger requirement for RAM, because you would have to move all of your changes temporarily to RAMdrive while the track was being recreated. It's still a col feature though.

Another thing, does anybody know if puppy is using UnionFS? From the description I assume it has to be, but it doesn't really say anywhere that I see.

The /home is on the USB drive, so any changes saved are saved there. I wouldn't think it would be as hard as the situation where you have to deal with RamDisk to store you changes back to a CD-RW cdrom.
