If the pnd is mounted, and then you update the pnd while already mounted.. I think the correct term would be 'the behaviour is undefined' Probably depends how you did it, or how your updater did it; did it download a fresh copy with a temp name, and move it over the existing one? In which case open files would staty against the old (now missing) one, but new opens would get the new one. So it would depend on how aufs handles it.
Also, since I don't squashfs these guys.. they're just iso's .. maybe it works better .. maybe a squashfs'd one would just blow up?
Hard to say.. theres a few layers at work here. Best not to mess with a file while it is mounted, though
Messing with the appdata is no biggy of course ..
Imagine mounting an iso in windows, osx .. and then screwing with the .iso while also having the directory opened in a mount? who knows..
(a pnd is essentially an iso, mounted so writebacks go to appdata.)
