Anaconda uses zram to allow installation on low memory systems.
We used to have a custom script called "zram-stats", that can be
used to test and debug zram usage during installation.
The script no longer works & zramctl now provides much better
output than our script ever did. So we decided to decommission
the old Anaconda provided script & use zramctl instead.
So change the cleanup rule in the Lorax boot.iso template
to keep the zramctl utility.

This new setting for 'find_multipaths' tries to prevent things like
LVM from going ahead and activating LVM on the individual disks/paths
until there is reasonable certainty (via a timeout) that the device
is not a component of a multipath set.
NOTE: 'smart' is supported by device-mapper-multipath v0.7.7 and later.
This creates a tar suitable for use with the anaconda kickstart liveimg
command. It adds the kernel, grub2, and grub2-tools packages to the tar
template.
The filesystem was too small because Anaconda always adds the kernel,
but the template uses --nocore so it doesn't take that into account.
Add it to the template so that the filesystem size will be large enough
to hold the extra packages.
You can now set the keyboard layout and language. Eg.
[customizations.locale]
languages = ["en_CA.utf8", "en_HK.utf8"]
keyboard = "de (dvorak)"
Existing entries in the kickstart templates are replaced with the new
ones. If there are no entries then it will default to 'keyboard us' and
'lang en_US.UTF-8'
Includes tests, and leaves the existing keyboard and lang entries in the
templates with a note that they can be replaced by the blueprint.
For example:
[customizations.timezone]
timezone = "US/Samoa"
ntpservers = ["0.pool.ntp.org"]
Also includes tests.
This removes the timezone kickstart command from all of the templates
except for google.ks which needs to set it's own ntp servers and timezone.
If timezone isn't included in the blueprint, and it is not already in a
template, it will be set to 'timezone UTC' by default.
If timezone is set in a template it is left as-is, under the assumption
that the image type requires it to boot correctly.
xorrisofs needs to use iso-level 3 when creating images with large
files. This adds tests to all the relevant templates, just like we used
to do for udf and mkisofs.
This is based on the VHD compose type, with the following differences:
* Use the vhdx format instead of vhd
* No WALinuxAgent
* Install hyperv-daemons
The hyperv-daemons are activated through udev rules, so there is no need
to add them to the services line.
It was substituting _ which didn't match what pungi uses for creating
the DVD. Make things consistent and use - as the replacement character.

In order to support iso creation on multiple arches with the templates
we need to be able to select different packages based on arch.
lorax-composer uses the arch-specific Lorax templates in order to
generate the output iso so this patch:
1. Creates a new template and type to parse it, live-install.tmpl
which contains only installpkg commands and #if clauses for arch
2. Removes bootloader related packages from the live-iso.ks
3. Remove dracut-config-rescue exclusion because it can cause problems
with some blueprints.
4. Switch logo requirement to system-logos which is satisfied by
generic-logos or fedora-logos. This prevents conflicts when a blueprint
installs fedora-release-workstation.
So in the future, if x86.tmpl, etc. need a new package to support
creating the iso it should be added to the correct section in
./share/live/live-install.tmpl
If a package is excluded in the template and later added by a blueprint
or dependency, anaconda will fail to finish the installation. So remove
the -dracut-config-rescue exclusion and instead remove the rescue
artifacts in %post
Some platforms, like ppc64, require that the /boot partition be present.
It doesn't hurt to have it there on other platforms so instead of trying
to add per-arch kickstart templates just use reqpart --add-boot
everywhere.
Some platforms do not have grub2, and some require other partitions.
Anaconda will add platform specific partitions if the 'reqpart' command
is included, and it will add bootloader specific packages to the list if
they are needed.
This is required to ensure that SELinux is configured properly while
building. It fixes the problem with building tar, and should be
installed in the other image types for consistency.

Most bootloaders used in Fedora already have BootLoaderSpec but extlinux
doesn't yet. So when using extlinux the old grubby must to be installed.

Some files are created in non-reproducible way, including including
random data explicitly (/etc/machine-id), timestamps (fontconfig cache,
ldconfig aux-cache, certs cache), or entries in random order (groups,
systemd catalog, package list).
Fix this by either making the files reproducible, or removing them.
Images don't work without these fixes:
* Enable Network Manager.
* Disable cloud-init.
* Add Hyper-V modules into initramfs.
Fixes specific for RHEL:
* Create ifcfg-eth0 required by waagent.
* Install python3 and net-tools required by waagent.
Recommended changes:
* Use recommended kernel boot args.
* Disable kdump.
Since these images can be used to create multiple machines, they should
not have a unique machine-id attached to them. Replace /etc/machine-id
with an empty file so that it will be regenerated at boot time.
If we leave the root account w/o a password people will use it that way,
leading to insecure images. Also if we use a default password. So lock
the root account in the templates.
Users will need to do one of these things:
1. Use [[customizations.user]] in their blueprint to configure root or
another user.
2. Use [[customizations.sshkey]] to set a key for root
2. Install a package that configures a user at install time
3. Install a package that sets up a user at boot time (eg. cloud-init)
This also drops the auth line from the kickstart templates, allowing it
to use the default password algoritm instead of md5.

This differs from lmc's --make-ami in that creates a full disk image instead of
an fsimage. Create a raw disk image with a / and /boot partitions, and enable
sshd, chronyd, and cockpit by default.
