This could help to keep the disk size down during installation,
if the FS within the VM is also supporting TRIM.

This adds the --repo command which can be added multiple times to point
to dnf .repo files.
--enablerepo and --disablerepo can be used multiple times to control
which repos from the .repo files are actually used for the boot.iso
creation.
--repo can be used instead of --source, or in addition to it.
This requires OVMF to be setup on the system, and for the kickstart to
create a /boot/efi/ partition. You can then use it to create UEFI
bootable partitioned disk images.
Make the metavars useful, not STRING. Simplify some of the error
checking, let the parser handle it. Add type=os.path.abspath to several
path arguments so that relative paths will be converted to absolute
paths when they are processed.
One of the most useful things to override is the path to the templates,
this adds a cmdline option to do that instead of needing to create a
whole configuration file and pass it.
This adds support for creating Vagrant boxes using virt-install. It also
includes an example kickstart that sets up the vagrant user with the
default ssh key.
The default result, without passing --image-name, is in
/var/tmp/vagrant.tar.xz
This implements the bundle spec from:
https://github.com/opencontainers/specs
It creates a tar with the filesystem under /rootfs/ and includes user
provided config.json and runtime.json files.
The size estimate was counting the /EFI/BOOT/ contents twice and then
doubling that. Only count things once, then double it for the
System/Library/CoreServices/ copy.
hard-links don't work. With CoreServices hardlinked to /EFI/BOOT/ the
Mac won't boot. With /EFI/BOOT/ hardlinked to CoreServices grub2 cannot
read the config file so there are 2 real copies.
This reduces the image size from 21M to about 12M
The system the image boots on will likely not match the host where lorax
was run, and in some cases this can cause systems to hang.

After the cleanup step, check that everything in /usr/bin and /usr/sbin
can still run. Currently, this just checks that ELF files have
everything they need to link, and scripts have an interpreter.
Verifying is on by default but can be skipped with --noverify
I originally added --add-template to support doing something similar
to pungi, which injects content into the system to be used by default.
However, this causes the content to be part of the squashfs, which
means PXE installations have to download significantly more data that
they may not need (if they actually want to pull the tree data from
the network, which is not an unusual case).
What I actually need is to be able to modify *both* the runtime image
and the arch-specific content. For the runtime, I need to change
/usr/share/anaconda/interactive-defaults.ks to point to the new
content. (Although, potentially we could patch Anaconda itself to
auto-detect an ostree repository configured in disk image, similar to
what it does for yum repositories)
For the arch-specfic image, I want to drop my content into the ISO
root.
So this patch adds --add-arch-template and --add-arch-template-var
in order to do the latter, while preserving the --add-template
to affect the runtime image.
Further, the templates will automatically graft in a directory named
"iso-graft/" from the working directory (if it exists).
(I suggest that external templates create a subdirectory named
"content" to avoid clashes with any future lorax work)
Thus, this will be used by the Atomic Host lorax templates to inject
content/repo, but could be used by e.g. pungi to add content/rpms as
well.
I tried to avoid code deduplication by creating a new template for the
product.img bits and this, but that broke because the parent boot.iso
code needs access to the `${imggraft}` variable. I think a real fix
here would involve turning the product.img, content/, *and* boot.iso
into a new template.
pylorax unconditionally calls reset() on the dbo, so provide an empty
method to keep it happy.
The lmc dbo is minimal because it is only used for creating the iso, not
anything related to package installation.
The stage2 image can be either LiveOS/squashfs.img or it can be
images/install.img, adjust the IsoMountpoint for this and rename the
flag to .stage2 instead of .liveos
--cachedir allows the user to specify where the DNF cache is located.
This doesn't actually appear to do much since dnf erases the cache when
it is done. May be useful in the future.
--workdir sets the top level directory for lorax to use for installing
packages, creating installtree and installroot. Normally a temporary
directory under /var/tmp.
Note that the workdir will *not* be removed if there is an error setting
up the DNF object.
--force skips checking if the output directory exists, allowing things
like pungi to use lorax to place the output next to the repo tree it has
already created.
This is a workaround for a current dnf bug, it doesn't update the state
of the packages after they are installed so we tear down the base dnf
object and create a new one pointing to the installroot.
There is an additional issue with the list of files returned, hawkey and
dnf don't appear to make a distinction between files, dirs and ghosted
dirs like yum did, this can result in too much being removed (eg. all of
/etc/selinux/) so we only remove files not directories.
pylorax users will need to change to using dnf and pass a dnf.Base()
object as the dbo argument instead of a yum object as the yum or ybo
argument. See the lorax script for an example of how to do this.
The lorax cmdline argument --excludepkgs has been removed since dnf
doesn't appear to have any way to support it and packages should be
controlled using templates anyway.
The directory where the --logfile is located is also used for other log
files and for the anaconda logs when using --no-virt. Create the parent
directories if they don't exist.
--make-pxe-live target generate live squashfs and initrd for pxe boot.
Also generates pxe config template.
--make-ostree-live is used for installations of Atomic Host. Additionally to
--make-pxe-live it ensures using deployment root instead of physical root of
installed disk image where needed. Atomic installation needs to be virt
installation with /boot on separate partition (the only way supported by
Anaconda currently). Content of boot partition is added to live root fs so that
ostree can find deployment by boot configuration.
Previously if there was an error during a novirt installation that
didn't exit the process there was no way to detect it. This uses the new
--remotelog option for anaconda to monitor the logs for errors using the
same criteria as it does when monitoring a virt install. If there is an
error the anaconda process will be terminated and the logs will be
gathered up into ./anaconda/
Recently, Fedora has been trying to do a 3 product split. As part of
that, lorax was changed to do "installpkg lorax-product-*" via
provides.
I think that approach is awkward; a much simpler approach is to simply
specify the product package as input to lorax on the command line, via
external rel-eng scripts.
This patch therefore adds --includepkg (and we should probably add an
option to remove the implicit lorax-product-* glob).
The aarch64 change to use shim (6907567) also stopped using mixed-case
names for BOOT${efiarch}.efi (so it's always .EFI and ${efiarch} is X64
IA32 AA64 etc. now), and mkefiboot needs to match that.

The ppc config files were missing from the live config_files directory

When using GPT it reserves a few more sectors at the end of the disk for
the copy of the GPT so pad the size of the partitions in the kickstart
by 2MiB instead of 1MiB to account for this.
Depending on the environment that --no-virt is run inside the resulting
filesystem may need to have the SELinux labels updates. Run setfiles on
the new filesystem after the anaconda run has finished.
eg. when run from inside mock the labels will be incorrect.
This no longer seems to be needed, and causes images created without
passing --vnc vnc to start up with a serial console. If you need a
serial console you can pass it using --kernel-args
Add check for running traceback script and when the retry fails.
This also indicates something went wrong with the installation, exit
when they are seen in the logs.
Also drop looking for WARNING in the regex errors, they will be errors
after the syslog level name remap patch goes into anaconda.
Spaces cause various bugs like #923374 and #855849 , and it would be
better if we just didn't use them.
Note that there's a corresponding pungi change to go with this.

Watch the logs for WARNING packaging: .* requires .* which indicates
that there are missing packages and it is sitting at a prompt waiting
for user input.
What I need is to make something like the traditional DVD which also
includes packages. At present this is apparently handled by the
entirely separate pungi tool.
At the moment for me, it's the least bad option to modify lorax to
inject data from an external source than to create a new tool, or
attempt to also modify pungi to do this.
This would also allow pungi's DVD creation to eventually be a set of
external templates for Lorax.
If the user supplies a fsimage to use for the iso it may not be on the
same filesystem as the working directory. Try to hardlink first, but if
that fails copy the image.
This adds the --make-tar option which will produce a xz compressed tar
of the root filesystem. This works with either virt-install or no-virt
modes. Use --image-name to set the output filename.
--compression is used to set the compression type to use, which defaults
to xz. Supported types are xz, lzma, gzip and bzip2.
--compress-arg is used to pass arguments to the compression utility.
--make-fsimage was only working with --no-virt, this re-structures
things so that virt-install partitioned disk images can be converted to
a fsimage. --make-ami was actually already doing this, so change it to
use --make-fsimage and set the default image name to "ami-root.img" with
a label of "AMI".
This also adds the ability to set the fs label on iso fsimage and
fsimages created with --make-fsimage and --make-ami by passing
--fs-label, but note that bootable iso's expect the Anaconda label.
When doing an image install there is no .buildstamp file to pull the
information from so use the cmdline variables (or their defaults) and
pass them to anaconda in the environment.

Fix "lorax -V" and add a "version is ???" to the log file so we can easily know
what version of lorax is used to build an iso.
Changed to try/import for versioning because the version file is autogenerated.
This adds support for installing to a filesystem image instead of a
partitioned disk image. It requires Anaconda's --dirinstall support.
Also re-organized the code to break it up into smaller methods.
This speeds up iso creation in no-virt mode by removing the need to copy
the filesystem from the partitioned disk image to the filesystem image
that is used to make the squashfs image.
--location specifies an iso directory tree to be used by virt-install
instead of the iso. This allows you to update the initrd in the tree for
debugging.
virt-install uses the images/pxeboot/ directory for initrd.img and
vmlinux.
An iso is still required for the LiveOS/squashfs.img stage2 file.
live media isn't exactly the same as the Anaconda install media. Right
now this amounts to needing a root= cmdline argument but in the future
there may be other differences.
This also reverts 5437557846 on the new copies of the templates.
Switch to using execWith* so that the command and its output can be
logged. To capture the output setup a logger named "program"
livemedia-creator captures all of this into program.log

From Harald Hoyer <harald@redhat.com>:
pollcdrom is used to poll for the install medium. A lot of CDROM drives
are not polled by the kernel correctly, so we have to actively poll for
the medium.
This adds support for creating an appliance description file for the
disk image. Mako templates are used to make it easy to support other
appliance targets. The included example works with virt-image.
When running with no-virt mode libvirt and virt-install are not needed
so make the import optional and update the usage info reflect that the
virt options are disabled.
There's a small amount of additional metadata required for the Mac boot
images to appear as bootable devices in the startup preferencs, so add
support for generating that.

AMI images are un-partitioned filesystem images with a grub.conf that
is read by the pv-grub bootloader used by EC2. Most of the actual work
making the AMI is done in the kickstart. This just creates the image
file.
Fedora 17 changes top level directories like /bin, /lib, etc. to
symlinks to the corresponding dirs in /usr/
dracut can convert old systems to the new layout using its convertfs
module.
In the latest method for booting the rootfs is in the LiveOS
directory of the media, not appended to the initrd. Detect this
and mount the iso and pass the CDLABEL to virt-install.
Some repos may contain anaconda packages for more architectures,
so it's not possible to get the right buildarch.
This patch allows optional specifying of the buildarch on the
command line when running lorax.
If the buildarch is not specified manually, lorax tries to get
it from the anaconda package as before.
If there's no anaconda package in the repository, don't fallback
to the system architecture and continue, because this is pointless.
We need the anaconda package.
This runs anaconda directly, using the --image install feature. The host
system should be the same release as the target system in order to avoid
unexpected problems.
