Thank you for the report. We are looking into this. Also hit the same issue in rhcos 42.80.20190801.1 image on openstack. Hope could get a quick fix. Can you post a copy of `cat /proc/cmdline`? We suspect that putting `coreos.no_persist_ip=1` may fix this. Either way, I would like to see a the kernel commandline for an interesting edge case. On the bootstrap: [core@bootstrap-0 ~]$ cat /proc/cmdline BOOT_IMAGE=/ostree/rhcos-529e69b461fac3e465bba244eb757a14ba85d29277018bd01f8336a2640d6521/vmlinuz-4.18.0-80.4.2.el8_0.x86_64 console=tty0 console=ttyS0,115200n8 rootflags=defaults,prjquota rw root=UUID=138ead55-3c06-4d76-95f9-f671ff2ab8ab ostree=/ostree/boot.0/rhcos/529e69b461fac3e465bba244eb757a14ba85d29277018bd01f8336a2640d6521/0 coreos.oem.id=qemu coreos.oem.id=vmware ignition.platform.id=vmware Can you try by appending `coreos.no_persist_ip=1` to the kernel commandline? Yeah, there's no easy way for VMWare users to change the initial kernel commandline right now. The fix for this merged in https://github.com/coreos/ignition-dracut/pull/98 and we're working on getting it into a RHCOS update. Should be fixed in 42.80.20190809.0 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Actual results: Expected results: Additional info: Compare with rhcos-410.8.20190516.0, no such issue, /etc/sysconfig/network-scripts/ifcfg-ens192 is not pre-existing in image, so ignition could successfully create ifcfg-ens192.
