I included two script lines into the startup file that call a file named "postinit.sh" from /tmp/mnt/storage and create it if not exists. It is meant to add startup customization on the fly without touching the firmware image. You can easely edit this file by telnet copying it from a network shared usb pendrive or sharing the internal storage with samba. Note that the script is executed in sync mode and not launched as a background task, so if you need to add time consuming commands you should embrace all your code into brackets and follow them with an ampersand like this:
( echo Time consuming example task
&& sleep 300
) &
or create your own script and launch it async
/tmp/mnt/storage/myscript.sh &
As the name suggest, postinit.sh it is executed AFTER all init tasks executed by the stock firmware.
You should be aware that if you exec commands that block access to the router you actually won't be able to recover unless you access it by serial console which requires to buy a few hardware and soldering some wires. I strongely suggest you all to experiment with this script calling your custom code from a different script saved on external usb drive so if something go wrong you can easely remove usb pendrive and fix the script on your pc.
I also included a newer busybox-mips binary with a huge additional amount of useful commands. You have it in the path so simply type busybox-mips and you will get the usage help with the list of commands.
Again, I think this shouldn't be considered a mod firmware, so I try to keep as untouched as I can. I hope that the task of modding postinit script will be too difficult for not experienced users, so they can't brick their devices.
Let me know what you think about that,
Enjoy :cool:
