[MOD][init.d] Swap Partition[TUTORIAL]

Backup your sdcard
This mod needs an kernel with swap support
This tutorial implies that you have already partitioned your sdcard

Q: Why use a swap-partition instead of a swap-file?
A: You are able to mount your first partition on computer, with swapfile you are not.

mmcblk1 = external_sdcard if you use mmcblk0 you will hardbrick your phone. Some apps like swapper 2 use mmcblk0pX as default value, if you want to use these apps make sure to change this in settings.

1. Find your swappartition

fdisk -l /dev/block/mmcblk1

Output:

Code:

---

              Device Boot Start    End        Blocks  Id    System
/dev/block/mmcblk1p1          1    3849      30916015+    c    Win95 Fat32 (LBA)
/dev/block/mmcblk1p2      3849    3880        250084  82    Linux swap

---

2. Activate Swap (Linux swap)

swapon /dev/block/mmcblk1p2

3.Optional change swappiness

echo 10 > /proc/sys/vm/swappiness //default value is 60

4. Test if all works

free //There should be some numbers behind swap

cat /proc/sys/vm/swappiness //current swappiness value

5. init.d script

Code:

---

#!/system/bin/sh
swapon /dev/block/mmcblk1p2
echo 10 > /proc/sys/vm/swappiness
