Introduce a new section in NETWORK-BOOT-TROUBLESHOOTING.md addressing issues where boot stops after start4.elf, detailing necessary config.txt settings for kernel and initramfs. Include instructions for ensuring the presence of required files in the TFTP root and a command to verify configurations on the LXC. Update initrd.img to reflect changes in the network boot process.
