Is this sort of thing really appropriate for local.conf though? Shouldn't we 
be encouraging people to create a distro config for this level of 
customisation?

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

Why is sysvinit included in both DISTRO_FEATURES and
DISTRO_FEATURES_BACKFILL_CONSIDERED? My understanding is that
BACKFILL_CONSIDERED only makes sense when the value is not included in
DISTRO_FEATURES.

[OE-core] [PATCH 2/2] local.conf.sample: Document HOW-TO enable systemd or busbox to replace sysvinit

[Khem Raj]

OE core provides systemd,busybox as options for system init system along
with sysvinit being the default. Document the needed settings to enable
systemd and busybox as options if user wishes.

There are two possibilities. one where its pure systemd no sysvinit, in this 
case
we should have DISTRO_FEATURES_BACKFILL_CONSIDERED += “sysvinit” and remove
DISTRO_FEATURES_append.

In case where we want sysvinit scripts also be there and systemd can execute on 
them
then above setting is needed as it is. Option 2 is what I have tried to put in 
there
