Hello! I would like to share some knowledge about Atrix 2, especially about using the KitKat port by alteredlikeness on it. If you want to install the ROM on System 1, you face some problems with free space. There is no space to install Google Apps, even the micro modular one. Fortunately, there are unused partitions on the device, like /cache and /preinstall. We can benefit from using it.
Also, I recommend installing custom ROMs on JB Leak 3 firmware. It has better partition layout than the stock ICS (big data partition, relatively small cache partition).
Let's go straight to the facts. To offload the system apps to /preinstall partition you need to edit this file:
/system/etc/bmm/script/boot.sh

remount /system as read-write and add the following code after this line:
Code: 
/bb translate -i $MNT $BLK $STR $SYSN > $1/init.fs.rc

this needs to be added:
Code: 
  echo exec /bb mount -o remount rw /system                               >>$1/init.fs.rc
  echo exec /bb mkdir -p /preinstall/system/app                           >>$1/init.fs.rc
  echo exec /bb mkdir -p /preinstall/system/priv-app                      >>$1/init.fs.rc
  echo exec /bb cp /system/app/* /preinstall/system/app                   >>$1/init.fs.rc
  echo exec /bb cp /system/priv-app/* /preinstall/system/priv-app         >>$1/init.fs.rc
  echo exec /bb rm /system/app/*                                          >>$1/init.fs.rc
  echo exec /bb rm /system/priv-app/*                                     >>$1/init.fs.rc
  echo exec /bb mount --bind /preinstall/system/app /system/app           >>$1/init.fs.rc
  echo exec /bb mount --bind /preinstall/system/priv-app /system/priv-app >>$1/init.fs.rc

On each reboot, it will look for apps in /system/app and move them to /preinstall/system/app and bind that folder to /system/app. Binding works stable, symlinks are not working at all in this case. Don't know why, apps always crashed if I used symlinks.

This all is useful if you want to install custom ROM on System 1.

OK, the jb leak idea is great unless u have the at&t a2 (in which I do). So what are the negative impacts of using this script rewrite? Any boot failure?

---------- Post added at 02:49 PM ---------- Previous post was at 02:34 PM ----------

Also, how to remount /system as read-write? And can I just "copy/paste" what u posted?

No man it's not working properly. I was on JB leak, followed the exact procedure mentioned by you. Now there's always some leftover from previous roms and it causes force close loop. I tried formating /system, /data and /cache too. Nothing. guess I'll have to start with FXZ

How did you edit the boot.sh file? Maybe your text editor has messed up the end-of-line character? It should be in Unix format.

Also, if you change roms, /preinstall folder must be cleared before installing new rom, then there will be no leftover.

I used es explorer with rw perm for system. And yes I definitely used UNIX format. Big size gapps work without removing BMM but whenever I install new rom, the apps from previous roms were present and caused constant Force closes. Also, formating system, data and cache from BMM dosen't work. Any idea why because I can't use Mokee and JBX on sys1 because of size limitation.
THANKS in advance:highfive:

So I have to wipe /preinstall from explorer right? I'll try that! Thanks a ton!

EDIT- It works! Thanks man! I think we gotta market this thread. It's very useful for us sys 1 users!
