Default Use internal sdcard as dalvik-cache

As I cannot use the internal sdcard with CM11, I've made a small script which mounts the internal sdcard as /data/dalik-cache to get more free space for apps & app-data.

WARNING: Only for users who are familiar with adb as you can probably brick your device!

Installation is a bit tricky, maybe someone makes an installer. All steps are done over adb

First format the internal sdcard with ext4: mke2fs -t ext4 /dev/block/mmcblk0p23
Copy script below to /data/local/userinit.sh (e.g. adb push userinit.sh /data/local/userinit.sh)
chmod 755 /data/local/userinit.sh

Reboot and let dalvik cache recreate. After this happend, reboot into recovery, wipe dalvik-cache and enjoy the 200MB more free space in data for apps.

busybox mount -t ext4 -o noatime,nodiratime,nosuid,nodev /dev/block/mmcblk0p23 /data/dalvik-cache;
mountext=`busybox mount | egrep 'ext2|ext3|ext4'`;
if [ -n "$mountext" ]; 
busybox chown 1000:1000 /data/dalvik-cache;
busybox chmod 771 /data/dalvik-cache;

Awesome... I just needed it for assigning block on dalvik in my beta app. Works great!
