First of all, i was offering an explanation, nothing more and i haven't insulted you or anyone else.
But this isn't xda and thankfully we are usually spared the hacked together misrepresented roms you can find elsewhere. This is my final word on that issue.
Now, about trimming. Plenty of people prefer a minimal system partition and a larger data partition for apps. You can download as many ringtones and wallpapers as you want to your sdcard and they will be available for all future installations. There really is no good reason to have them on your system partition. If you for some reason feel a NEED to have them on your system partition then just use root explorer to copy them there.
Well your explanations are very cheerful.
i've been using root explorer to put that back in my system partition and i don't feel the NEED to put them on my system partition but i PREFER them on my system partition cause i got PLENTY OF SPACE,
The rest goes to sd card and never had problems with that.
Hoping it's really your final word.
