I try desesperately to push an app with adb on the /system/app folder (to install the PlayStore on my low cost tablet). So i tried to remount the /system partition with root rights  :

mount -o remount,rw /system 

But it give me everytimes the same response :

mount: Read-only filesystem

And i tried also with this command  :

mount -o remount,rw -t ext4 /dev/block/actc /system

but it's the same thing... And i don't understand really why, even with the root user, i can't modify this...

So if someone have an idea, it could be save one person in distress :p
