[Q] init.d support for stock rom P500 - Optimus One, P500, V General

Hi, I just read some tips about using script for enhancing performance.
It says that the script must be places in system/etc/init.d
But in stock rom P500 (GB 2.3.3 v20G) I can't find folder init.d
The questions:
1. Is the stock rom already support init.d script execution?
2. If yes, will it works just by creating folder init.d and place script there?
3. If not, how to enable support init.d for Optimus One, stock ROM rooted?
I search this forum and find some guide about init.d support in other phone models, will it works on Optimus One too, or perhaps it needs particular way to do it?

1. No
2. If you have init.d support in rom.
3. Only way to do it is cook a custom rom through kitchen to add init.d support

3. answer is some wrong:
you doesnt need to cook a custom rom, you only need the adb (android debug bridge) to "speak" with your phone:
0.) on your phone download busybox from market
1.) install android sdk on your computer
2.) install LG usb drivers on your computer
3.) open a console (on windows use the "cmd" command)
4.) remount "root" to read/write (type following commands in the cmd)
Code:
adb shell
mount -o remount,rw /dev/block/mmcblk1 /
exit
5.) retrive the init.rc file from your device: (type the command in the cmd)
Code:
adb pull /init.rc C:\users\XXXXX\Desktop\init.rc
6.) open the init.rc file and add the busybox command to execute scripts in the /system/etc/init.d folder
after the lines that does mkdirs etc but BEFORE zygote starts (this stars the whole android)...
Code:
service userinit /system/xbin/busybox run-parts /system/etc/init.d
oneshot
7.) close and save the file, push it back to your device, than reboot:
Code:
adb push XXXX\XXXX\init.rc /init.rc
now you can use the init.d folder as in CyanogenMod / other custom roms.

Dear Andy,
Thanks 4 the procrdure, however i wanted to ask you whether there is any tool to check that the scripts in the init.d folder r getting executed?

That works? I mean init.rc is in ramdisk in boot partition, and gets unpacked on boot, so any changes in / are lost on reboot - at least that is what was told to me.

Option 1 - run logcat during boot (Trough ADB, type logcat in adb shell, a little simpler if using Droid Explorer)
Option 2 - Run a script that changes something that was previously different. Try installing the supercharger (with different from normal minfree values), rebooting and running the script again to make sure the minfree values are modified. If so, init.d is working and vice versa.

I go directly to this step, using root explorer on phone (not using PC+ADB)
But after reboot, init.rc i've already edited before has been restored again to original value, as said by Tasssadar.
Maybe I should do it using PC+ADB instead of direct edit on phone?

you are trying to modify a running system, sure - you have to do such things
in the boot.img file and have to re-flash it. there is no way to modify a running
system, sorry for misunderstanding.

go to your recovery, make a backup of your current system and connect the
phone via usb to your computer and copy the rom from the phone to your computer.
then, use the htc kitchen to modify the created rom / or the boot.img
