Add --include-directory option
--include-directory makes the header files installed in the container
available on the host. This is useful when running a language server
such as clangd in the mkosi container. If we define a path mapping
in clangd from /usr/include to the include directory, we can jump
to all the header files of external dependencies in the include
directory right from the editor.

Allow build script to read from stdin when running in a script
When running language servers like clangd via a mkosi build-script,
we need clangd to be able to read from stdin to interact with the
editor. By default, systemd-nspawn doesn't do this for security
issues but in this case we trust the build script so we can specify
--pipe to enable the build script to read from stdin.

Arch: Switch back to using a single call to pacman
We shouldn't be working around dependency issues in Arch. I'm not
getting any failures using this anymore right now but if any turn
up, we should file bug reports for the relevant Arch packages to

not a group, the burden to add it as a dependency should be very
minimal.

fix bootable CentOS 7 efi by using grub2-efi
First of all the `systemd-udev` package does not exist in the CentOS 7
repository and thus will cause the `dnf` step to always fail.
The `bootctl` / `systemd-boot` feature in CentOS 7 is very broken and
does not work.
To create bootable CentOS 7 EFI images, this commit switches to
`grub2-efi`.
Furthermore it will fail early if unified kernel images were not
explicitly disabled via the commandline switch. They are simply not
supported by grub.
There are some quirks when an EFI image is being built on a non-EFI
system, since grub2 will check for existence of `/sys/firmware/efi` and
only create an efi-compatible boot config if that directory exists.
Otherwise it will generate 16bit `linux16` and `initrd16` boot
entries, which are obviously incorrect. This is subsequently fixed
by patching the generated file.
Also the `grub2-efi` setup requires a more ellaborate nspawn setup,
just like `clr-boot-manager`

extend mkfs to support adding cmdline args

The e2fsprogs packaged within CentOS 7 is very old and does not support
the `metadata_csum` ext4 feature.
This commit explicitly disables this feature upon filesystem creation.
Otherwise all e2fsprogs utilities will not work or misbehave within the
created image. (e.g. `tune2fs -l`)
Additionally this commit explicitly enabled the `64bit` feature for ext4
on supported architectures. Previously this might or might not have been

allow optional override of GPT first-lba header
Usage of this feature is totally optional and the defaults are actually

However there might be a reason to override this, e.g. if the created

first-lba value. One example would be the `prl_disk_tool` utility from
the Parallels virtualization suite.

CI: Add QEMU boot tests
Adding these gives us a clear idea of which setups should work and which
are broken. This helps with triaging issues since we can immediately see
if a setup is supposed to work or not. It also makes sure setups that do
work keep working in the future.
Currently, only Arch, CentOS and Fedora can boot on all included setups
(nspawn, UEFI + systemd-boot with unified kernel images, UEFI +
systemd-boot and BIOS). Debian, Ubuntu, OpenSUSE and Mageia fail
on UEFI without unified kernel images because their package managers
don't install any boot loader entries that systemd-boot can read.
Photon doesn't work on any of the setups. Clear also has a lot of issues
due to it using its own bootloader and OpenMandriva has QEMU failures.
For now, we disable all these but we hope support by them can be added
by interested contributors in the future.
