[Buildroot] (apparently) HUGE kernel

[Buildroot] (apparently) HUGE kernel

[Robert Urban]

Hi Folks,

I'm trying to build a modest linux-2.6.28.7 kernel for a VIA C3 based
router/firewall which will boot from CF-card.

I've removed everything I can think of that is superfluous for my
application, things like virtualization, various things to support SMP,
almost all debug options, etc.  I've only left the IPV4 networking,
netfilter, QoS, a bit of USB support, etc.

Still the kernel (bzImage) is 12MB large.  gah.  On my Fedora10 system the
kernel is 2.5MB large.  A 12MB kernel isn't the end of the world, but it
just seems too large.

I would be grateful if someone could have a look at my config-file and
possibly offer an explanation.  The config file is here:

cheers,

Rob Urban

as someone pointed out (thanks again), my bzImage includes the initramfs,
which is controlled by

	CONFIG_INITRAMFS_SOURCE="..."
