##   # Currently the files we check only need to be available on x86_64 and aarch64
##   architectures: x86_64 aarch64

# This test runs on both FCOS & RHCOS. The initrd includes specific files which,
# if omitted from the image, will cause some failures with certain Ignition
# configs. This test doesn't assert the functionality of any files, it
# simply gives a high level check to see if the files are available.
