I've finally found a workaround : the LIVE_CHROOT_BUILD variable wasn't
defined anywhere, preventing installation of resolv.conf file before to
build binary image. I've got my live system with :
  env LIVE_CHROOT_BUILD=enabled ./make-live <my-options...>

but anyway, I wonder what is the good method to debug live-helper
