Changes for openSUSE / SLE:
* ignition-mount-initrd-fstab.service / ignition-umount-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-touch-selinux-autorelabel.conf:
Trigger SELinux autorelabel after Ignition runs; Ignition would support
SELinux itself, however this is a compile time option, so it can't be
used here.
* 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.
