Comment:
@q66 Your suggestion worked flawlessly with packages explicitly depending on `linux` and `linux-headers`. E.g. `cdemu-client` and of course `dkms`.

Its a nice and simple workaround/feature of `xbps`, so I think I'll close the issue.

Still hoping for _optional dependencies someday_, but that's an `xbps` thing...;)
