What it does have:
No .odex files (deodexed)
ext manipulation files and libs, so it makes it easier to e2fsck or tune2fsck if you want ext4.
Also thanks to eugene373 for his work in establishing a baseline update.zip without which this would have taken a great deal more work.
Should work in clockwork, doesn't seem to need a wipe. If you have problems, use regular recovery, just rename it to "update.zip" on the root of your sdcard and it should flash just fine.
This should be completely safe. Nonetheless, should loss of job/loss of fertility/nuclear war ensue, I am not responsible.
1. Load the .zip file onto the root of your internal SD card (/sdcard)
2. Using Clockwork recovery, do "Install zip from SD card", then "Choose zip from sdcard", choose the VibrantDeodexed.zip, and choose "Yes"
2b.(ONLY If you don't have Clockwork) rename the download to "update.zip" and place it on the root of your sdcard. Then reboot into recovery and choose "Update packages".
3. (Optional) Flash JAC's kernel with ODIN using the directions specified HERE It is more stable and gets better benchmarks but there do seem to be some issues with the screen taking a while to wake up.
NOTE: The first boot takes a long time because it has to dexopt stuff.
