Changes for openSUSE / SLE: * ignition-mount-initrd-fstab.service: Upstream Ignition will only mount partitions or subvolumes explicitly mentioned in the Ignition configuration. A default SUSE system, however, is split over several subvolumes, and most users won't want to define all the partitions again. On the other hand a lot of core functionality (e.g. configuring a SSH certificate for the root user or adding a configuration file) requires access to those subvolumes. For better usability in addition to Ignition's own mount / umount stage all files systems tagged for being mounted in the initrd ("x-initrd.mount" mount flag) will automatically be mounted / umounted. * ignition-setup-user.service / ignition-setup-use.sh: The user configuration can be stored on a device with the label "ignition" (e.g. by attaching a USB flash drive with that name) instead of using the platform specific configuration storage mechanism. * ignition-userconfig-timeout*.conf: Set timeout for Ignition device so boot will just continue if no physical Ignition configuration device is attached (e.g. when using platform specific configuration). * ignition-suse-generator: Supplements the upstream generator by adding dependencies to ignition-setup-user.service and ignition-mount-initrd-fstab.service. Additionally it will try to autodect the platform if it is not set on the kernel command line. * 02_ignition_firstboot: This file has been part of upstream ignition-dracut, but has since then been moved to a static CoreOS specific configuration (https://github.com/coreos/coreos-assembler/pull/616); it is now used in a modified version adapted to SUSE's needs. This script will automatically set the kernel parameters to trigger an Ignition run if a flag file does not exist (e.g. on first boot). To trigger an Ignition run manually just delete the file "/boot/writable/firstboot_happened". * ignition-firstboot-complete.service: This file has been part of upstream ignition-dracut, but has since then been moved to a static CoreOS specific configuration (https://github.com/coreos/fedora-coreos-config/pull/1087); it is now used in a simpified version adapted to SUSE's needs. Sets the flag file "/boot/writable/firstboot_happened" to indicate a successful first boot. This flag file is evaluated by the GRUB script 02_ignition_firstboot from above. * ignition-enable-network.service / ignition-enable-network.sh: Ignition supports detection whether the configuration requires networking to avoid having to boot with networking enabled even when it isn't necessary; the actual implementation to start the network is left to the distribution. * ignition-kargs-helper: Distribution specific helper script to implement kernel argument support.
