Lightweight livecd - packages.

[Celso Suzuki]

Hi,
I'm trying to build a lightweight livecd with a minimum selection of packages.
I'm trying these packages :
%packages --nobase
@core --nodefaults
net-tools
-aic94xx-firmware*
-alsa-*
-biosdevname
-btrfs-progs*
-dhclient
-dhcp*
-dracut-network
-iprutils
-ivtv*
-iwl*firmware
-kexec-tools
-NetworkManager*
-plymouth*
-postfix
-selinux*
-libvirt
-gnome-boxes
-selinux*
-man*
-nss*
-openldap*
-nss*
-libselinux*
-popt*
-slang*
-numactl*
%end

But with these list the livecd don't create the files vmlinuz0 and initrd0.img. And the USB didn't have the option to boot the kernel.
So, I need to insert in the list the anaconda package ... but with anaconda, the file squashfs.img file raise almost 250M. From 110542848 to 349351936 bytes. From 196 packages to 436 ...
Does anyone know what I realy need to create the  files vmlinuz0 and initrd0.img ?
I just need a small kernel running from a ramdrive.

Detail .... 
If I overwrite the squashfs.img file from the minimum kernel, withou anaconda over the file with anaconda, it boots and run. I could use these, but I'd like to create the ISO without fixing or changes ...

Thanks in advance
