This moves everything except the cmdline checking into run_creator in
pylorax.creator
It also rearranges some functions to prevent import loops, and adds a
utility function to imgutils (mkfsimage_from_disk for copying a
partition into a filesystem image).
This reduces the amount of code in livemedia-creator to the cmdline
parsing and calling of the installer functions. Moving them into other
modules will allow them to be used by other projects, like the
lorax-composer API server.
Previously lorax had no way to use repos with self-signed certificates.
This adds the --noverifyssl cmdline option which will ignore certificate
errors.

This controls how big the root filesystem is for the squashfs used in
the boot.iso, the default is 2GiB.
Note that larger rootfs sizes will require more memory and may cause the
build to fail.
DNF doesn't want users to access base.logging anymore.
Lorax already takes over the "dnf" logger and directs it to ./dnf.log,
so it wasn't really being used.
This raises the debug level to DNF's custom DDEBUG, and sets it up so
that dnf.librepo.log and hawkey.log are next to dnf.log
Before attempting to cleanup any dangling anaconda mounts copy the
anaconda logs to their final location.
Also, catch failures to cleanup the mounts, log it, and continue trying
the other mountpoints. A cleanup failure will result in an InstallError
instead of a CalledProcessError.
Fedora now has a edk2 package so use the OVMF code from there. This also
adds using a copy of OVMF_VARS for each boot instead of reusing the one
provided by the package.
In some cases the initramfs may not be present in /boot to save space.
Use it if present, otherwise use the kernel version to recreate the name
of it.
This also fixes problems with dracut running out of space when not using
--live-rootfs-keep-size
This makes sure the contents of /boot are at the expected locations in
/boot and in sys_root. For partitioned images it mounts the separate
/boot partition on /boot. For both fsimage and partitioned images ir
binf mounts it to sys_root so that the kernel+initrd can be found.
The boot directory isn't always named boot.0, so wildcard it and let the
count check handle failure if there is more than 1.
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.
Resolves: rhbz#1318958
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.
