Modify the first-boot script and documentation to set the EEPROM boot order to 0xf21, prioritizing eMMC boot followed by network boot. Adjust network boot settings for faster failure on DHCP timeouts and update related scripts and documentation to reflect these changes. Enhance the rescue script to directly modify EEPROM settings without requiring a chroot into eMMC, streamlining the recovery process for devices stuck in network-only boot. Update relevant documentation to ensure clarity on the new boot order and its implications.
