a1905c3b4b Add --dracut-arg support to lorax
Use it to override the default dracut arguments (displayed as part of
the --help output). If you want to extend the default arguments they
all need to be passed in on the cmdline as well. eg.

--dracut-arg='--xz' --dracut-arg='--install /.buildstamp' ...

7fa009c66e Move core of livemedia-creator into pylorax.creator
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).

fc56671638 livemedia-creator: Move core functions into pylorax modules
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.

3485fe462c livemedia-creator: Always copy novirt logs before cleanup
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.

9b151ec2bd Update ostree boot handling
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.

b91e79d9bc livemedia-creator: Check selinux state and exit
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.

6798f7c5ec livemedia-creator: Fix off by 1024 error
commit 4699c88109 changed how the disk
size is estimated and not all users took into account that the return
value is in MiB.

3e9efdcf48 livemedia-creator: Change fsck.ext4 discard failures to errors
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.

4699c88109 livemedia-creator: Create runtime using kickstart partition size
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.

f8316a7b89 livemedia-creator: Use qemu instead of virt-install
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.

7c0a6dffd6 livemedia-creator: Stop passing --repo to anaconda (#1304802)
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.

ba4218ea98 livemedia-creator: Make sure the rootfs.img can be compressed
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.

33d008d9f2 livemedia-creator: Fix calculation of disk_size in some cases
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.

0d22b72615 livemedia-creator: Raise an error if url is used without networking
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.
