# We use net.ifnames in cloud environments
# no_timer_check is something we're cargo culting around
# console= args are also for clouds
# The other ones are for Ignition and are also in image-metal.ks;
# change them there first.

# By default, we do DHCP. Also, due to the above disabling
# of biosdevname/net.ifnames, this uses eth0.
# The DHCP_CLIENT_ID="mac" bit is so that we match what dhclient
# does in the initrd, and the DHCP server gives us the same lease
# if possible. See https://github.com/coreos/fedora-coreos-config/issues/58.
