[Q] Using EXT4 Partition makes folder permissions go nuts and unable to R/W
Basically, it's a permissions problem. I've tried using Permissions fix on CWM but with no luck. As FAT doesn't have a permissions subsystem, seems like there is no problem with it, but as EXT4 has it, everytime the phone creates a new file/folder, it cannot read its own file.
Although I can connect and see the files on the computer, they're marked with a padlock. It means I don't have permission to access it.
I can regain access to the file and the phone can read it back again, but it's a pain in the place if everytime the phone creates a file, I have to put it back to the computer and redo the permissions sets. It can't even view it's own files. I've already tried to set the SD card root permission to myself, and with everyone capable of read/write access. But unfortunately, newly created folders aren't affected by this.
As far as it looks like, it creates a 'user' for every app that makes the file.
For example, the folders on that picture were created by the camera software, so the user of both is "10041 - user #10041". It has R/W access, but nobody else has access to even see what's inside.
I really enjoyed the transfer speeds with EXT4 (I'm on Ubuntu 12.04), even inside the phone and outside, using USB cable and apps feels snappier. I don't want to go back to FAT32..
I'm using a Motorola Atrix 4G and Morrisoft CM7 latest buid (Custom ROM).
Just to clear things up: Device CAN read and write files under EXT4, but it trips on its own tail by settings permissions badly.
