[OE-core] systemd PACKAGECONFIG = "lz4" leads to broken init

[Marcus Hoffmann]

Hey Robert,

thanks for the patch. I'd like to understand how this fixes the problem
or probably more genrally how the PACKAGECONFIG thing works internally.

Can someone give me a pointer on where to look? It seems a bit like
magic just adding "lz4" twice at the end :-).

Kind regards,
Marcus
