4a4a415f88 Remove setfiles from mkrootfsimage
SELinux applies the correct labels, setfiles is no longer needed.
This allows lorax to run with SELinux in Enforcing mode.

080705e8e6 Remove SELinux Permissive checks
Anaconda, Lorax, lorax-composer, and livemedia-creator can all now run
with SELinux in Enforcing mode. It does not need to be disabled and if
there are denials they should be reported as a bug.

Log the current state of SELinux when starting, update the
documentation.

43ff505804 Add --no-system-repos to lorax-composer
Running lorax-composer --no-system-repos will prevent it from copying
the dnf repositories from /etc/yum.repos.d/ into the lorax-composer repo
directory. It will *only* use repositories setup using the sources api
or written to /var/lib/lorax/composer/repos.d/

If lorax-composer has previously been run without this switch the system
repos will need to be removed from the composer/repos.d/ directory. It
would also be a good idea to remove the cached metadata in
/var/tmp/composer/

af28b25e50 dnf changed the type of gpgkey to a tuple
And in an intermediate version it returns a VectorString object which
isn't serializable by the json or toml modules.

So convert it to a list so that the type is consistent in the sources
code.

eafc2796a1 Update depsolving with suggestions from dnf (#1636239)
The previous method worked, but wasn't exactly idiomatic. This is more
correct, and appears to work the same (templates depsolve, version globs
work, multiple repos work).

Note that this does use a private dnf attribute ._goal, but the word is
that this is going to become a public api soon, so yes it is there on
purpose.

6fb5910acd Fix directory creation for blueprints
Depending on how lorax-composer is run setting up an empty blueprints
directory can fail. So this moves checking/creation until after the
other directories are created and uses make_owned_dir to make sure

3499426b2d Change make_dnf_dirs to be run as root
It needs to be root in order to set the ownership and permissions on the
directories that are under /var/lib/lorax/composer/

Refactor the directory creation into a utility function, and use a umask
of 0o006 to ensure that the parent directories created do not have o+rw
set on them (makedirs behavior is different between Python 3.6 and 3.7
so umask of 0 doesn't work consistently).

d65a502861 Report an error if the blueprint doesn't exist
composer-cli uses TOML for 'blueprints save' which was returning an
empty 200 response if the blueprint didn't exist. Change this to return
a standard 400 error response if the blueprint doesn't exist.

composer-cli is already setup to handle receiving json when an error is
returned so just the toml API response for `blueprints/save` needed to
be changed.

ec47fe12a9 cli: Clarify error message for unprivileged access
`os.path.exists("/run/weldr/api.socket")` returns False for users which have no
access. This leads to composer printing that the file does not exist, which is
misleading.

Since it's no possible to distinguish the two cases, fix this problem by
combining them and showing a single error message.

8bc6282083 Don't try to append to DNF config value that can't take it
See https://bugzilla.redhat.com/show_bug.cgi?id=1595917 and
https://github.com/rpm-software-management/dnf/pull/1200 for
more on this. Briefly, DNF before 3.0 presented this config
value as a list...and mutating it worked. DNF from 3.0 until
3.6 presented it as a list...mutating it didn't work, but also
didn't *fail*, so this has actually not been doing anything on
DNF 3.x but we haven't noticed.

In DNF 3.6 values like this are presented as tuples instead of
lists, to try and catch usages like this, and it worked! We
need to change this one.

There is an additional weirdness here. tsflags is actually, in
libdnf terms, an OptionStringListAppend option: that means that
when something tries to *set* its value, the new value is just
appended to the existing list of values. This is very weird
behaviour when you're interacting with it like this, but
happens to be quite useful, as we can just 'set' the value to
a list like this and it will actually get appended (which is
what we want), and this one syntax happens to work correctly in
DNF 2.x, 3.0 through 3.5.1, and 3.6.

6e86328865 Always update repo metadata when building an image
When the kickstart is handed off to Anaconda for building it will
download its own copy of the metadata and re-run the depsolve. So if the
dnf cache isn't current there will be a mismatch and the build will
fail to find some of the versions in final-kickstart.ks

This adds a new context to DNFLock, .lock_check, that will force a check
of the metadata. It also implements its own timeout and forces a
refresh of the metadata when that expires because the dnf expiration
doesn't always work as expected.

891729528f Use rootpw for setting the root password instead of user
Ends up you cannot use the kickstart user command on root, since it
already exists, so we have to translate that into a rootpw command.

So [[customizations.user]] with name = "root" only support key, which
will set the ssh key, and password which will use rootpw to set the
password. plain text or encrypted are supported.

75400f6a7f Ditch all use of pyanaconda's simpleconfig
lorax uses pyanaconda's SimpleConfigParser in three different
places (twice with a copy that's been dumped into pylorax, once
by importing it), just to do a fairly simple job: read some
values out of /etc/os-release. The only value SimpleConfigParser
is adding over Python's own ConfigParser here is to read a file
with no section headers, and to unquote the values. The cost is
either a dependency on pyanaconda, or needing to copy the whole
of simpleparser plus some other utility bits from pyanaconda
into lorax. This seems like a bad trade-off.

This changes the approach: we copy one very simple utility
function from pyanaconda (`unquote`), and do some very simple
wrapping of ConfigParser to handle reading a file without any
section headers, and returning unquoted values. This way we can
read what we need out of os-release without needing a dep on
pyanaconda or to copy lots of things from it into pylorax.

9a83a5cb3f lorax: Only run depmod on the installed kernels
In the near-future there may be /lib/modules/ directories for older
kernels with weak dependencies listed. These may not match the installed
kernel(s) so we cannot depend on them to drive generate_module_data.

Instead use the existing findkernels() function to get the list of
installed kernels and iterate those, running depmod on them.

b0872c8f17 Make no-virt generated images sparser
At the end of disk image installs, use fstrim on the generated filesystem to
discard any blocks that were allocated during the install and are now unused.
This will allow tools such as qemu-img to create images that do not include
deleted data.

For raw disk images that do not go through qemu-img, use fallocate --dig-holes
to create sparse holes in place of the unused blocks.

The blueprints/changes API is a bit different from the others, the total

since there will be a different number of commits for each.

The function is passed the dict, and it can be used to select the total
to use for retrieving all of the results. If it isn't included it will
use data["total"] which works fine in most cases.
