[Buildroot] hardware detection

[Stefan Feilmeier]

Hello.

First of all buildroot is a really useful tool and we use it to build
the initial system for our install cd. The only problem is that I am
stuck on hardware detection. I am trying to store my kernel modules on
the cd and mount it during boot process to keep my initrd small. Modules
for the cdrom drive are compiled into the kernel. This is what I do
currently: 

1. Boot initrd
2. /etc/init.d/S10udev starts udev and populates /dev
3. Mount cdrom(s) on /mnt/cdrom/
4. Mount --bind /lib/modules

Till here everything works just fine and the modules are accessible
in /lib/modules. Now I try to run `udevtrigger` but it doesn't detect my
network card. Loading the module manually with `modprobe pcnet32` works
fine. I am trying this in a VMware virtual machine.

Does anybody have a hint for me?

Regards,
Stefan

1) delete udev and use busybox's mdev instead
2) echo alias eth0 pcnet32 >> /etc/modprobe.conf; ifup eth0
 or something to that effect.
HTH,

Thanks for your answer. The problem is that I need real hardware
detection as the cd will run on many different platforms and not only on
VMware virtual machines. Any idea?

I'm confident that there are numerous tools with varying dependencies to
accomplish that task.
discover (i use the one from debian) should do the trick, perhaps?
