Raspberry Pi 4B change USB boot order and hostname

This is really more a note to self so that I remember how to do things.

To change the boot order for a Raspberry Pi 4B:

sudo -E rpi-eeprom-config --edit

This opens up the current configuration.

Add in:

BOOT_ORDER=0xf14

to try to boot from USB first, then SD card.

BOOT_ORDER=0xf41

is the default, which will try to boot SD card, then USB.

More details on bootloader for Raspberry Pi 4.

On Ubuntu systems, to change the hostname:

sudo hostnamectl set-hostname newNameHere

Also,

/etc/hosts

should be edited to replace any occurrences of the old hostname with the new one. Then reboot. (Read about this method here.)
