Boot Raspberry Pi 4 / 400 from USB
Clone source disk (SD card) to a destination USB disk or disk which will be bootable. Ex:
root # rsync --force -rltWDEHXAgoptx /sdcard/ /pendrive/ root # sync
Configure kernel line to replace SD Card to new disk:
/boot/cmdline.txt dwc_otg.lpm_enable=0 root=/dev/sda3 rootfstype=ext4 fsck.repair=yes usbhid.mousepoll=0 rootwait consoleblank=0
change order of boot on EEPROM:
1 = Check SD card
4 = Check USB drive
f = Start again
Replace 0x1 to 0x4 and save.
root # rpi-eeprom-config --edit
Poweroff, remove SD Card and boot only using USB device.
Wi-Fi
Power saving mode was an issue years ago on older versions of the Raspberry Pi. Some people report Wi-Fi stability issues if power saving mode is active, even in newer versions. To permanently disable power saving mode, if you experience problems:
raspi # echo -e '#!/bin/sh\niwconfig wlan0 power off' > /etc/local.d/wifi-power.start raspi # chmod +x /etc/local.d/wifi-power.start
