[PATCH] systemd-boot: Add recipe to compile native

[Viswanath Kraleti]

systemd has ukify, a native tool, which will combine the kernel/initrd/stub
components to build the UKI (unified kernel images). systemd-boot recipe
isn't providing this tool.

To use ukify, one need systemd-boot native recipe so that a dependency can
be added on populate_sysroot task to get the tool under sysroot-native.

Why not call the recipe systemd-ukify then? systemd-boot doesn't provide more than that.

Then, when using ukify, one needs to have the .efi binaries from target systemd recipe which
for aarch64 are:

/usr/lib/systemd/boot/efi/addonaa64.efi.stub
/usr/lib/systemd/boot/efi/linuxaa64.efi.stub
/usr/lib/systemd/boot/efi/systemd-bootaa64.efi

and these could IMO be in a systemd-boot binary package because these files are not needed
in the main systemd binary package and rootfs.

The recipe itself looks neat and small, thanks!

For secure boot sbsign-native would be needed, but maybe a separate issue.

Cheers,

-Mikko

The description is superfluous. It is enough to say that we have to
provide ukify tool to build images for systemd-boot

I support the name systemd-boot-native, it links this tool to the
systemd-boot target package, the main user of the generated images.

systemd-boot recipe installs those files already. ssytemd-bootaa64.efi
goes to ${EFI_FILES_PATH}/${SYSTEMD_BOOT_IMAGE} in the package
(/boot/EFI/BOOT/), while addonaa64.efi.stub and linuxaa64.efi.stub are
installed to the DEPLOY_DIR. Indeed, they are not necessary on the
target system as one rarely builds a kernel on the OE rootfs. If the
need arises, we can probably add systemd-boot-stubs package, having
these two files.
