I've been playing around with the CM-mod/S7 and can sucessfully make it boot with all ext4 partitions.
Backround information:
Parititions and formatting
My proposal
What I propose is a modified version of CM9-mod with /cache and /data formatted as ext4 partitions.
I've already got a working version, the main issue is that:
I dont know what the difference is. I've ran quadrant with ext4 and again with ext4, and there's very little difference.
Since quadrant has an I/O and database benchmark (and they run on /data), at least it shows that there's only 1% change in scores.
Would anyone actually be interested in using an ext4 mod?
There are some downsides (depending on how you view it):
Backround information:
Parititions and formatting
- Partitions are the basic unit of storage on my devices with storage (think C: D: E: if you use windows)
- The standard layout of android devices:
- A /cache partition
- A /data partition
- A /system partition
- Other hidden partitions (this part isnt relevent to us)
- The common filesystem formats for recent android devices are EXT 3 and 4 (4 being the newer obviously)
- The S7's default partitions:
- stock 3xx: (ie froyo)
- /cache: ext3(?)
- /data: ext3(?)
- /system: ext2
- stock 5xx: (ie honeycomb)
- /cache: ext3
- /data: ext3
- /system: ext4
- my ext4 mod:
- /cache: ext4
- /data: ext4
- /system: ext4
- stock 3xx: (ie froyo)
- All other devices that launched with HC installed use all ext4 partitions.
- But the S7 didnt launch with HC, it launched with froyo.
- Dell couldnt upgrade /data to ext4 without wiping user data.
- They could upgrade system, since they wipe it on install anyway.
- Cache they didnt for the outside chance a user had actual important data in it.

There are some downsides (depending on how you view it):
- ext3 and ext4 nandroids arnt compatable
- You will need to do a fac reset on first install (as it reformats)
- You will need seperate versions of CM9-mod and CWM
