Which one are you using? If you've generated a rootfs.cpio, maybe
you've enabled the initramfs option, which as its name suggest is a
filesystem in RAM, which explains why your changes disappear after a
reboot.
Use a filesystem stored on persistent storage, such as a SD card, eMMC,
NAND flash or USB key.
Best regards,
Thomas
