Building initrd for custom ISO

[Renato Botelho do Couto]

I'm working implementing support for a hardware that requires one kernel 
change to have console working.  I already built a custom kernel that 
solves the problem and have console working.

Now next step is to build a custom ISO containing this kernel so it will 
be able to boot and run installer on fixed console.  I understand I need 
to build a custom initrd and copy it to /casper on ISO but I couldn't 
find any documentation about how to do it.

If anyone knows the steps to do it please let me know.

Thanks!
