It worked for me, weird.

Have you double-checked that you didn't make any errors in your file?

it works

seems that i had the \r\n problem cause i made the file with leafpad and now cat /proc/sys/vm/swappiness gives 30 after reboot

thank you very much n.n

wonder if adding "echo 4 > /sys/class/i2c-adapter/i2c-2/2-0063/region" in the script would change my region settings aswell

Don't echo in to files in /etc. It replaces the file's contents and the OS might become unbootable.

As root, you can however do "echo 50 >/proc/sys/vm/swappiness" without the quotes, and it doesn't modify anything permanently, reducing the risk of doing anything that makes your device unbootable.

My script has:

Radio Region change to world wide, vlaue 4
Swappiness level to 30

The script will automatically start up and activate those setting every reboot. So no need to touch rCS file.

Which avoiding people from breaking their device.

care to share the script?

The script doesn't work without root access.
But I now just going the old way with Bash Script instead.
Bash script works great without hassle but Python scripts cannot modifying the file due to permission level too high.

If you want my Shell Script auto start, I'm happy to send it to you :) or upload it here

I highly recommend to anybody who wants to change rcS - instead of that just create a file /etc/event.d/somename with following lines:

Code:

# my somename fix

start on started rcS-late

script
      echo 30 > /proc/sys/vm/swappiness
end script
... and insert any another wished lines after "echo 30" and before "end script"

This would not corrupt your N900 in case of problem and it allows the next Nokia OTA upgrade.


could you explain the instructions to do this, please?
