[Buildroot] CONFIG_BLK_DEV_INITRD deactivated on automatic build

[Dennis Borgmann]

Hello buildroot-list!

First of all - thank you for the work done for this project. It is
awesome and I really like it. Straightforward and quick to use.

I think, I found a bug. If you download buildroot and start configuring
your project with "make menuconfig" and after that configure the kernel
with "make linux26-menuconfig", everything seems to be ok. I did give it
a custom kernel-config named "/tmp/config-2.6.34".

After running "make", everything seems to be ok, but the resulting
kernel does not contain the option "CONFIG_BLK_DEV_INITRD". I need to
manually do a "make linux26-menuconfig" again and rebuild the kernel for
the resulting kernel to contain this option.

This was a really silly thing to find, took me around one week, because
you wouldn't think of such a mistake. Could it be, that this is a bug? I
am using buildroot-2010.08.

Kind regards,
Dennis

Yes, it was a bug. When "initramfs" isn't used as the target filesystem
format, we forcefully disabled the CONFIG_BLK_DEV_INITRD option. This
has been fixed post-2010.08, by the following commit:

 http://git.buildroot.net/buildroot/commit/?id=ee3f319249e146d92b093ad8c45a3a908d44236f

So you can either apply this patch on top of 2010.08, or use the latest
Buildroot git. We unfortunately do not maintain "stabilized" versions
of Buildroot (such as 2010.08.x) for the moment.

Regards,

Thomas
