BitDefender Rescue CD iPXE boot script (non-working because missing /bin/mount.nfs in initramfs)

echo Booting BitDefender Rescue ${bitdefender-version} x86 for ${initiator-iqn}

initrd ${base-url}boot/initfs.i386-pc
boot || goto failed
goto start

according to https://forums.fogproject.org/topic/13407/pxe-boot-bitdefender-rescue-cd-fails, the bitdefender init ramdisk is missing some .ko

I could reproduce their findings with:

• loop mount the iso
• loop mount the livecd.squashfs file
• extract the boot/initfs.i386-pc into a temporary place
• copy from the squashfs the /lib/modules/4.19.8-gentoo-x86/kernel/fs/{nfs,nfs_common} into the temporary place
• repack the new initfs
  find . -print0 | cpio --null --create --verbose --format=newc | xz -9 --format=lzma > /path/to/new.initfs and use that as replacement for the faulty initfs.i386-pc

ymmv :P

login as livecd, add a missing link sudo ln -s /mnt/cdrom/rescue / and startxfce4, add a nameserver to /etc/resolv.conf (echo 'nameserver 9.9.9.9'| sudo tee /etc/resolv.conf and start the bdgui tool..

ymmv, you can prefer cloudflare 1.1.1.1 or google 8.8.8.8
