Booting C programs!!

[asanka]

Hi everybody!
Is there any way to run a my own C program when booting linux? Actually I'm thinking about printing "Hello World!" and hold when I turn my machine on. Which configuration files I should edit or where I should put my program in the file system? Thanx!

Add it to the init script of the Distro
In arch this is /etc/rc.sysinit

If you want your system to really just give out that message and nothing else, try out the kernel "init=(your/program" option. (If you use GRUB as bootloader, you can directly edit the booting line when starting).

Then your application will be loaded and executed right after kernel initialization as the "master application". This means no other program like bash will be loaded.

Linux is made for Software Hackers by Software Hackers.
Meaning you can do ANYTHING, this might be a shock if you come from that one system were you are limited to what the company thinks you should do on your system

Linux (I should say Unix) is everywhere: Phones, DVD Players, Microwaves, TiVO and yes sometimes even in ATMs.
This is since you can Mod if how you want it.

Not only Linux is, I would like to point out.
For example, if you modify GNU GRUB, you not only have the last word, but also the first word your machine prints out after BIOS.

And with Coreboot, we now even start claiming the right to a say in the realm that has been regarded closed hardware for some decades
