Would you be willing to change the cmdline.txt to use the PARTUUID? Then the image won't need any modification to work between sdcard vs usb.
Yeah, I need to find a way to do this dynamically, because I'm guessing that the prefix would change every time the image is created, but that would solve the problem. Thanks, I didn't know about PARTUUID

This is a little rough. (no error checking.) But I figure you'll modify it for your scripts..

Code: Select all

#!/bin/bash

image=$1

kpartx="$(kpartx -av $image)"

read -d" " img_boot_dev img_swap_dev img_root_dev <<<$(grep -o 'loop.p.' <<<"$kpartx")
img_boot_dev=/dev/mapper/$img_boot_dev
img_root_dev=/dev/mapper/$img_root_dev
mkdir -p mnt/boot

PARTUUID=$(blkid -o export $img_root_dev | awk '/PARTUUID/ { print $1}')

mount -t vfat $img_boot_dev mnt/boot
sed -i "s/root=[^[:space:]]\+/root=$PARTUUID/" mnt/boot/cmdline.txt
sync
umount mnt/boot
kpartx -d $image

pgreco, thank you very much for all your work on Centos for RPi - I've been happily using 7 for a while and had been testing 8 in the latter part of last year. Will you be officially releasing Centos 8 for RPi now, or perhaps just stream? Just wondering if you're able to share any roadmap for it, given the Centos 8 announcement in December? Thanks in advance.

We need to ask this, does Raspberry Pi use Hamming code for error correcting like the x86-64 when equipped ....... if not then using the Pi for Linux is a lost cause because ANY single Bit error will cause a catastrophic failure when compiling....
A single Bit error can be caused by anything, magnetic fields from other electronics, your body, sun spots....

Windows has Hamming code style error correcting built into the OS that allow it to run trash code.... this is what made Windows the dominate user OS
