I'm not sure if lorax is creating the loop dev as write-protected, or if the loop-dev is provided to lorax, and then lorax falls victim.
The fact that the compose works when ran as root suggest that something outside of lorax is an influence to the outcome, as lorax runs as privileged root in mock.
This all began when aarch64.tmpl was enhanced to provide EFI support, it perhaps began to trigger code path that relates to loop-mounting with EFI.
Any insight you folks might have is appreciated. =)
Thanks,
