ignition-and-ostree.yaml

# Defines the "core" of a Fedora CoreOS like system; basically (ignition, ostree)
# plus other default tweaks.  Things in this file should be something we expect
# basically everyone using both Ignition and (rpm-)ostree to want.
# It may be used as an inheritance base by other projects like Fedora Silverblue or RHCOS.
# One good model is to add feodra-coreos-config as a git submodule.  See:
# https://github.com/coreos/coreos-assembler/pull/639

# Include rpm-ostree + kernel + bootloader
include: bootable-rpm-ostree.yaml

# Modern defaults we want
boot-location: modules
tmp-is-dir: true

# Required by Ignition, and makes the system not compatible with Anaconda
machineid-compat: false
