Please post a question in the question thread. And here you go.
The main benefits that ext4 has over ext3 are:
faster timestamping faster file system checking journaling checksums extents (basically automatic space allocation to avoid fragmentation)

There is a plethora of information on this. Please search first.

Ext3 and ext4 are linux filesystems that are unrelated to Android in general. You can probably find out more information on the pros/cons of each by searching specifically as a linux search rather than an android specific search.

No, trying to add additional code to framework files which exceeds /system partition space.
Dr.Honk answered my question. Not currently possible.

[ACS][CWM 3.0.25+]Rfs2Ext4 and Ext42Rfs **UPDATED 7/27

UPDATE:
There was a big in CWM that caused the date to change a good portion of the time randomly to the next day, causing the script not to be able to find the backup, and in some cases not finish the backup. I have fixed that, also in EG22 odexed the /system partition is too full to do a proper conversion so now the script removes the following packages:
Code:

Is what the title implies.. if you are running rfs flash the rfs2ext4.zip, it does a nandroid backup, converts to ext4, restores nandroid, clears dalvik, tombstones, and lost+found... then fixes permissions.
Running ext4? Flash the other zip to goto rfs with the same procedure...

Sorry for the noob question but this means rfs only builds can be converted to ext4?

No, this is for converting your filesystem from rfs to ext4 or vice-versa. If the ROM doesn't support ext4, this won't help you.

one instance where it will come in handy though.. is when you are on ext4 and want to flash an RFS only rom.. (like Gingerbread) you can flash this, instead of ODINing back to stock, then flash the new ROM

Chris... You might want to change the script for the rfstoext4 and change it to say please flash a rom instead of please reboot... That might confuse people....
Other than that it works great.. Nice job.
So if I'm on EXT4... flash .zip, then install RFS rom before reboot?
Thanks for answering my stupid question. I mess everything up, so I just wanted to double check.

When do I wipe data/cache? Before or after flashing this converter?
I'm assuming wipe data/cache, run conversion, then flash rom.
Thanks,
Chris

That would be the best way to do it, although since it backs up /data you should be fine with wiping after the conversion.

[Q] Create custom ROM from source

Hello,
I have been looking around and I can't seem to find how to make a custom ROM from source. Thanks for any help.

There are plenty of guides but it depends on the device you want to build for, what source you want yo build from.. Oh and what OS you want to use (but im guessing you are talking about android)

You will need a 64bit linux install (ubuntu is recommended) and 16GB of RAM+SWAP is recommended (and swap should be about twice your ram so 6GB RAM then a 10GB swap partition would be best)

You need to create a swap partition on your harddrive using the likes of gpart.
Then as long as its enabled in the kernel it should kick in
