This allows hacking on systemd without installing any build
dependencies except mkosi on the host machine.

## mkosi + clangd
[clangd](https://clangd.llvm.org/) is a language server that provides code completion, diagnostics and more
right in your editor of choice (with the right plugin installed). When using mkosi, we can run clangd in the
mkosi build container to avoid needing to build systemd on the host machine just to make clangd work.
All that is required is to run `mkosi` once to make sure cached images are available and to modify the path of the
clangd binary used by your editor to the `mkosi.clangd` script included in the systemd repository. For example, for
VScode, you'd have to add the following to the VSCode workspace settings of the systemd repository:
```json
{
"clangd.path": "<path-to-systemd-repository>/mkosi.clangd",
}
```
