Hey Henning,

I wanted to let you know that I've implemented the solution you suggested
and it worked like a charm. Using snippet files in
/etc/systemd/system.conf.d/*.conf and creating a custom package recipe with
the "dpkg-raw" class did the trick.

I appreciate your help and the example you shared. It was really useful and
helped me get things done smoothly.

Cheers!

Br,

Taneli
