Klin, I want to say a little more about why I want to go back to rfs for /system (see my prior post, right above this one).
I use Route 66 Maps and Navigation app. I have a friend with this player who told me his downloaded maps automatically went to the external sd card. I had not installed this app until AFTER I flashed the Icy Fusion rom. And my maps will NOT go to the external! They go to "SD card storage", as reported by Quick System Info Pro.
I know that one of the differences in this player with/without that rom is how /system is mounted, ext4 or rfs. So....even though this may have nothing to do with my map problem, I was trying to eliminate one possibility at a time. Once I revert to rfs, if it still fails to download maps to the external sd card, I don't know what to try next. So maybe you can help!
I'd still like to know how to revert to rfs, even if it doesn't fix my map problem. And if it doesn't, do you know what might be causing this with your Icy Fusion rom? I realize this is the thread for your kernel, not your rom. But to be honest, I'm not sure where the problem lies (but I think it's the rom)! That's why I was trying to eliminate things, one by one.
It's very easy to test. Just install Route 66 Maps and Navigation and download a map. You'll see that it goes to the internal, not the external sd.
Thanks very much.
