This is not really a guide to enable "S2e" in G300, I'll explain this stuff after the great INFUSION ROM will include this "upgrade".
UPDATE: If you like to do the same for ANY **STOCK** ICS see http://www.modaco.com/topic/356319-initd-userinit-on-stock-ics-roms/
UPDATE2: At post #9 you can found updated info for relase 020812 of INFUSION.
UPDATE3: Post #10--> set "mount as ext4" in S2e preferences!
The upgrade is very simple: INFUSION ICS ROM has "INIT.D SCRIP SUPPORT", but not "userinit" support. This is the real requirement for use S2e in your device. To add "userinit" support in your device you only need to do two steps:
1) Copy the file "20userinit" from a CM7/9 ROM to the directory "/system/etc/init.d/" (I include one attached to this post; remember: chmod 777, chown root:root)
2) Create the directory "/data/local/userinit.d/" (chown system:system)
And that's all! With this you can enable "userinit" support on your device and you can install and use S2e on it (I recommend to format to ext4).
I hope that Tillaz will include this feature soon.
