Unexpected behaviour you saw

I'd like to have a mkosi.init script to run at the very beginning (before config parsing/validation) in order to create/initialize the contents of things like PackageDirectories and ExtraSearchPaths. The specific usecase I have in mind is building systemd as part of the mkosi build, and including the systemd packages into the image built by mkosi. My attempt at that involved cloning systemd in the mkosi directory, and then adding a mkosi.sync with mkosi --directory=systemd --release=41 -t none to build it. However, this runs too late, and mkosi ends up failing because the build directory doesn't exist yet.

Used mkosi config

[Distribution]
Distribution=fedora
Release=41

[Content]
PackageDirectories=systemd/build/mkosi.builddir/%d~%r~%a

[Host]
ExtraSearchPaths=systemd/build/mkosi.builddir/%d~%r~%a

mkosi output

‣ systemd/build/mkosi.builddir/fedora~41~x86-64 does not exist

Obviously, a workaround for this is manually running mkdir systemd/build/mkosi.builddir/fedora~41~x86-64 before attempting to build, but that's an additional manual step I'd like to avoid if possible.
