Trigger Reinstall/Reprovision

Is there a way to trigger a reinstall or reprovision on bare metal (for when the ignition or combustion config) changes? One possibility seemed to be setting ignition.firstboot on the kernel commandline but wiping the rootfs using ignition (it is possible to wipe/formate root like this on CoreOS) produced a PAM error. On Fedora CoreOS, I believe this is possible using `coreos-installer`. -- Abhinav Praveen
