CoreOS does not process ignition files on a system that has MMC as the only storage device

I would be happy to provide detailed logs
CoreOS was PXE installed with options:
KERNEL fedora-coreos-30.20190801.0-installer-kernel APPEND ip=dhcp rd.neednet=1 initrd=fedora-coreos-30.20190801.0-installer-initramfs.img console=tty0 console=ttyS0,115200n8 coreos.inst=yes coreos.inst.text=yes coreos.inst.install_dev=mmcblk0 coreos.autologin=tty1 coreos.autologin=ttyS0 coreos.inst.image_url=http://10.20.30.2:8000/fedora-coreos-30.20190801.0-metal.raw.xz coreos.inst.ignition_url=http://10.20.30.2:8000/bare_metal_ignition.json IPAPPEND 2

bare_metal_ignition.json was generated with fcct with the below YAML file

Some of these groups don't exist on FCOS. Here is the default group list we use for the `core` user (i.e. if you don't specify your own core user): https://github.com/coreos/fedora-coreos-config/blob/testing-devel/overlay.d/...
Note that the `core` group gets created when the `core` user is created so you don't need to specify that group.

Hi Dusty, Thanks for the hints. They were very helpful. I did the following things to get it to work correctly:
1. I renamed my user account to "core2" - this fixed first part of the problem. This also included the updated group info. 2. I removed the /etc/hosts file creation as it was useless and conflicting with the actual generation. 3. modifying just /usr/lib/ignition/user.ign and rerunning coreos-installer did not work. I started with PXE boot and reinstalled the image with the updated ignition files. 4. *fcct* tool *-o *option does not overwrite the file. It tries to incorrectly update the JSON file and messes it up. So, forcefully removing the JSON/ign file and recreating it from YAML file works. - maybe I will file a bug against this.
Thanks again for your help

Sounds good. Yes please file a bug.

No problem. Are you unblocked now?
Dusty
Yes - unblocked for now.
Bug was filed - https://github.com/coreos/fcct/issues/42 and also fixed a few minutes ago - https://github.com/coreos/fcct/pull/43
