with IRC feedback from RP and others. Its more of local.conf.extended
item. So I have moved it in there in my v2 patch currently under test.

https://github.com/kraj/openembedded-core/commit/78edec042a47814ffb465d3c6c326fcd2e45447f

poky .e.g works well with both sysvinit and systemd
and some other derived distros as well. So think more it may be
that putting this sort of information in nodistro conf in OE-Core may
be another option but extended local conf is quite advanced user experience
as well
