chroot has invalid user permissions for network booting

[tomwardill]

I'm trying to build an image that I can PXE/netboot. As such, I don't need the final image, the filesystem chroot should be sufficient.

However, that appears to have all the file permissions owned by the user that ran rpi-image-gen, rather than the proper permissions where applicable.

I'm not sure if I can see anyway to fix this, or how the final image when it's generated has the correct permissions.
Am I missing something or doing it wrong?

Hi @tomwardill
Issues like this require information about your build environment, eg native, container, emulated, etc and ought to be backed up by some kind of log file showing your build output.

I'm currently running a filesystem tgz created by rpi-image-gen as a container via podman. Permissions are absolutely fine:

If you see unexpected filesystem ownership / permission issues it's usually caused by the environment in which podman runs in when it does the build.
#26 (comment) might help you diagnose.
