z4mod started as a modest idea - as a new Android user I wanted to ditch RFS in favor of a real filesystem. But thanks to the great support of XDA users and testers, z4mod grew and evolved, and it is now a very ambitious project - To allow any kernel be rooted, patched, customized, and yes - replace RFS with a filesystem of your choice. z4mod aim is to provide standards to the choatic SGS platform.

z4mod is a set of three seperate utilities:

• An automated kernel patch that will allow the kernel to mount partitions to filesystems other than RFS.
• Android recovery scripts to convert the partitions from RFS to other filesystems - "update.zip" files.
• A z4mod apk to apply a lagfix.

The online kernel patcher aims to allow anyone without any knowledge of linux the ability to patch a devices kernel in a simple manner. It also provides users with an easy to use web interface tool to create customized update.zip files.

Howto use:

Patching the kernel.

To patch a zImage file and enable non-RFS mounts on it, use:

$ ./z4build.sh

The above command will show you the usage help. Usually you will use z4build like this:

$ ./z4build.sh zImage recovery root

The above command will patch the zImage kernel, and add a new recovery binary, followed by adding 'root' functionality to the zImage.

Creating update.zip for converting.

To create update.zip file use:

$ ./z4zipgen.sh

This will show you the usage help. Usually you will use z4zipgen.sh like this:

$ ./z4zipgen.sh ext2 root busybox

This will create an update.zip file which will convert the RFS filesystem to ext2 and install root and busybox to the target system.
