How to change /system and /data partition sizes

Hello.

On our VAR-SOM-MX6Q (512mb nand flash version) we've installed Android KK4.4.2. Unfortunatelly, there is not much data storage available.

root@md_70:/data # df

Filesystem Size Used Free Blksize

/dev 385.8M 136.0K 385.7M 4096

/sys/fs/cgroup 385.8M 12.0K 385.8M 4096

/mnt/secure 385.8M 0.0K 385.8M 4096

/mnt/asec 385.8M 0.0K 385.8M 4096

/mnt/obb 385.8M 0.0K 385.8M 4096

/mnt/shm 1024.0K 0.0K 1024.0K 4096

/system 321.9M 308.9M 13.0M 4096

/data 66.6M 29.3M 37.3M 4096

/cache 7.6M 20.0K 7.6M 4096

/device 7.6M 20.0K 7.6M 4096

/mnt/shell/emulated 66.6M 29.3M 37.3M 4096

Is there any possibility to change partitions layout that /system will occupy less space (and I will remove some apks/odex files before creating image) and that way for /data there will be more space available? I'm using nand-recovery.sh script from Yocto SD Card to flash module. I see there you're using nandwrite command with proper /dev/mtdX. I suppose I need to change mount information about mtd devices and how they are formatted, but can't find place where I can do this.

Well, that was pretty easy - just change sizes in ubinize.ini and remove packages from system/app and system/priv-app that system would fit new partition size.
