I'm running MIUI 2.3.16 on the A1, but I guess this applies to any GB rom, so I'm opening a new thread.
I've always been annoyed at how the free space on /data just seems to get filled up on it's own, even if I'm not installing new apps. So I decided to have a look around with root explorer, and what I found out is that the culprit is the dalvik-cache, that resides on /data/dalvik-cache. The annoying thing is that while /data gets filled up with apps and dalvik cache, the /cache partition is EMPTY. It has only 1.44 mb occupied out of 75mb!
So I tried to move the dalvik-cache to /cache, but I'm having trouble. I tried to use Darktremor's A2sdGUI that has a function to move dalvik-cache to /cache, but it doesn't work, after the phone restarts the dalvik-cache is still on /data.
So I then tried to just create a symlink manually: I deleted the /data/dalvik-cache folder, and replaced it with a symlink to /cache/dalvik-cache.
But this doesn't work either, because when you reboot the system resets these folders and links, by re-creating /data/dalvik-cache folder and creating a link from /cache/dalvik-cache to that folder (while what I would like to do is the opposite!).
Can anyone help me figure this out? (if it is even possible?)
