The configuration variables for the Ignition configuration also serve as
data source for coreos-cloudinit config data (which includes plain scripts).
Document them properly and also call out that the networking variables only
work if coreos-cloudinit data is used.
For some use cases, too few networking variables were available. Add secondary
routing variables for the main network interface and add a second interface.
The user can only login via SSH if no password was set and can't login
over the VGA console in the web UI. To login the user needs to press
reboot and then append flatcar.autologin to the kernel command line parameters
in GRUB each time. The user may also not know that this option even exists.
Set flatcar.autologin by default in the kernel command line parameters for
VMware so that users don't need to set this themselves.
Update gdb to 9.1, and add --without-libmpfr-prefix to configure.
Since we should remove gdb from portage-stable, we need to update gdb
to 9.1 in coreos-overlay.
Change the default Kernel version of Alpha to 5.4, the most latest
LTS Kernel tree.
Also update patches and kernel configs, so it could build with the
new Kernel.
There was a logical mistake in Ignition that caused ignition.config.*
only to work when it was part of the ovfenv. Thus they were added but
the old CoreOS variables marked deprecated and kept. With both as OVF
variables each of them worked but directly specifying ignition.config.*
as guest variable still didn't because of the logical mistake.
Now there is a fix and both work well when specified directly as guest
variable (https://github.com/flatcar-linux/ignition/pull/11).
Delete the old CoreOS OVF variables because they just clutter the UI
and only the Ignition variables should be used in the UI.
We should enable the USE flag `selinux` not only for
`app-emulation/runc`, but also for `app-emulation/docker-runc`.
Otherwise, runc will be built without `BUILDTAGS=selinux`, so
runc is not able to detect selinuxfs of the system.
When setting up flannel interfaces, use MACAddressPolicy=none, so that
the MAC Address used is the initial one set by the kernel and not the
one assigned by systemd.
See coreos/flannel#1155 for more information.
In #279 we tried adding the MACAddressPolicy=none setting to the
existing 50-flannel.network file. But the change should have been in a
.link file, not a .network file.
When setting up flannel interfaces, use MACAddressPolicy=none, so that
the MAC Address used is the initial one set by the kernel and not the
one assigned by systemd.
See https://github.com/coreos/flannel/issues/1155 for more information.
Now that we started independent releases, we do not have to
check out upstream coreos branches.
Just check out the default branch for the repository, and rely
on the revision commits/branches for our release branches.
