Adding preseeding and firmware to wheezy iso netinst

[Mathieu Parent <math.parent@gmail.com>]

(Please cc me)
Hello d-i team,

I want to use the current Debian installer (7.0 Beta4) hybrid ISO
netinst but when I add a preseed.cfg file, EFI boot doesn't work.

What I need:
- Boot on CD-ROM Legacy (BIOS)
- Boot on USB Legacy (BIOS)
- Boot on USB EFI
- Boot from other modes?
- Add a preseed.cfg
- (sometimes) add some firmware files

Steve told me to use xorriso as found in the .disk/mkisofs file but I
didn't succeeded.

Having a simple tool to do this would be useful, like:
mkdebianiso --preseed=preseed.cfg --firmware=firmware-bnx2_*_all.deb
--firmware=firmware-qlogic_*_all.deb
debian-wheezy-DI-b4-amd64-netinst.iso

What I have done so far:

# Some vars
DEBIAN_ISO_VERSION='wheezy-DI-b4-amd64'
DEBIAN_DIR_VERSION='wheezy_di_beta4'
mkdir ~/mk_debian_inst
cd ~/mk_debian_inst

# Get ISO and preseed
wget http://cdimage.debian.org/cdimage/$DEBIAN_DIR_VERSION/amd64/iso-cd/debian-$DEBIAN_ISO_VERSION-netinst.iso
wget http://autoserver/d-i/wheezy/preseed.cfg # Local webserver

# Some deps
sudo aptitude install bsdtar xorriso syslinux-common

# Extract iso
mkdir cd
bsdtar -C cd -xf debian-$DEBIAN_ISO_VERSION-netinst.iso

# Preseed:
mkdir irmod
cd irmod
gzip -d < ../cd/install.amd/initrd.gz | \
    cpio --extract --make-directories --no-absolute-filenames
cp ../preseed.cfg preseed.cfg
chmod +w ../cd/install.amd/initrd.gz
find . | cpio -H newc --create --verbose | \
        gzip -9 > ../cd/install.amd/initrd.gz
chmod -w ../cd/install.amd/initrd.gz
cd ../
rm -fr irmod/

# Auto boot after 5 sec
chmod +w cd/isolinux/
sed -i 's/^timeout 0$/timeout 50/' cd/isolinux/isolinux.cfg
chmod -w cd/isolinux/
chmod +w ./cd/isolinux/isolinux.bin
