I carefully highlighted it in the cover letter: https://listman.redhat.com/archives/libguestfs/2022-May/028826.html > I've intentionally avoided introducing "--no-selinux-relabel" *in > addition* to "--selinux-relabel".

The problems I outlined above remain. What happens if someone passes both options? Are we supposed to continue documenting "--selinux-relabel"?
