Hi Thomas, It's not entirely clear that what I was trying to express was understood. Then in short:
1) A file ./src/build/images/kukui/R94-14125.0.2021_08_05_1510-a1/chromiumos_base_image.bin is created 2) It seems that commands use a variable called GCLIENT_ROOT and it's value is set to /mnt/host/src 3) When trying to create the loopback device the script tries to use a path /mnt/host/src/rc/build/images/kukui/R94-14125.0.2021_08_05_1510-a1/chromiumos_base_image.bin which does not exist 4) I'm stuck trying to figure out why GCLIENT_ROOT can't be set to the actual mounted filesystem path so that the image can be found and the loopback device created, etc. Then I assume I could create a block device use losetup with the correct path. So I'm debugging the script. There may be some details related to chroot and GCLIENT_ROOT that I don't understand. Let me know if I need to re-read your email.
