Use 4k blocks for the ext4 filesystem. Run fsck on the filesystem to
make sure deleted blocks are actually zeroed, and pass -Xbcj to
mksquashfs.
4k blocks and -Xbcj decreases the size by 2-6% depending on the
filesystem size. Zeroing the blocks of the ext4 fs improves things
dramatically. The problem is that DNF downloads the rpms before
installing them. In addition to forcing us to use a larger filesystem
than we would like it leaves data that is difficult to compress on the
image. The downloaded files are removed, but need to be zeroed out so
that mksquashfs can compress it.
Instead of reusing --image-name add a new argument to name the iso. This
way the disk image can be given a unique name with --image-name and the
iso can be named something different.
This option removes all the extra build artifacts from --make-iso,
leaving only the boot.iso
It also supports naming of the final iso with --image-name
If the kickstart includes multiple definitions for the same mount point,
the last one defined is used. The current code includes all of them in
size calculation, and the image file that livemedia-creator makes is big
enough to hold all of the partitions, even though the duplicates are
ignored by Anaconda.
Also alias --qcow2 to --image-type=qcow2
This allows --make-disk to be used to create any disk image that
qemu-img supports, not just raw or qcow2. See qemu-img --help for a list
of the supported image types.
Because livemedia-creator is using a media based installation by default,
no networking is brought up automatically. If then the url installation
method is used, it fails with an unclear reason.
This patch adds a check to raise a clear error if the url installation
method is used insisde the kickstart but no networking is configured.

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.
Resolves: rhbz#1258498
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.
