Re-run provisioners with previously built image

I’m using packer to build EL (i.e. Rocky, Alma, etc.) images using that distro’s Anaconda installer (of course).

While working and iterating on provisioning scripts, is there a quicker way to try fixes than to have to rebuild the entire image again from Kickstart? Having to wait for that for every provisioning script change is a real productivity killer.

Ideally I’d like to give packer a flag/option to say not to re-build the image but use the one that exists from the previous run.

Any way to achieve that?
