If an anaconda no-virt run crashes it can leave things mounted under
/mnt/sysimage. Previously anaconda-cleanup was used to handle this, but
it will also try to cleanup host mountpoints which isn't desired.
When an image name hasn't been passed, and the compression type is
something other than xz, the default image name should use the user
specified compression suffix.

Some cases of mksquashfs were not using -Xbcj when it is available for
the arch. This adds a function to return the correct args based on the
arch and the cmdline args.
lmc --no-virt was switching selinux to permissive if it was enforcing
and restore it when done. This works fine when it is the only session
running, but would cause problems if it was run in parallel.
It now only checks the state and exits with an error if it isn't already
disabled or in Permissive mode.
Users will need to run setenforce 0 before running lmc.
commit 4699c88109 changed how the disk
size is estimated and not all users took into account that the return
value is in MiB.
This would result in qemu based iso installations having a rootfs.img
that was 1024x too large.
Something is causing problems with the ext4 rootfs.img when running with
no-virt inside koji. This results in a failed image that looks good
until you try to boot it.
make_squashfs will now return False if it fails, and make_live_image
will return None (instead of the result path). lmc will exit with a 1
and log an error.
When using no-virt the runtime filesystem size comes from the kickstart.
For virt installs lmc was creating a runtime filesystem that was just
slightly larger than the space used by the files installed by anaconda.
This can run into problems with larger filesystem. It is also
inconsistent behavior between virt and no-virt installations.
With this commit the virt runtime filesystem will also come from the
kickstart.
Switching to using qemu directly allows lmc to be more flexible. It can
now run from inside a mock chroot for creation of all image types,
inculding disk images, and can take advantage of KVM on the host system
if /dev/kvm device is present inside the mock.
It should also be possible to create cross-arch images, but without kvm
available this is likely to be a very slow option.
When running a no-virt installation it was parsing the kickstart url
method and passing it to anaconda using --repo which prevents it from
working with url --mirrorlist method. There is no good reason to do
this, anaconda gets the method directly from the kickstart when it isn't
on the cmdline.
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 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.
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 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
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
