Hi Colin,
For the dhcp problem, what you need is a network manager. Any network
manager that supports dhcp would do the job. systemd-networkd might be
sufficient in your case.
For the local.conf problem, you could use a layer to manage all common
things shared by the team.
For the package adding problem, it depends on the purpose.
1) if adding the package is only for local work (dev or test), do it in
local.conf
2) otherwise, do it in image recipe
Distro conf files are not suitable for such kinds of modification.
Best Regards,
Chen Qi

Yes, I’d agree with that, Rick.
We run automated regression builds from a fresh version control
checkout – but because local.conf is generated when the build
environment is set up, it isn’t suitable for version control. So any
mods to it found during development have to be (remembered to be) put
into local.conf.sample, so that the same build is assured for anyone
anywhere.
I’ve long felt/assumed that local.conf was for truly local mods, for
that user and/or for their temporary try-outs.
Similarly – and this is going even more off-topic so I’ll save the
detail for a separate thread – I’ve still not yet got to grips with
whether, when I want to add a particular package, I should be
modifying my image recipe or set up a custom distro)

I was wondering about this recently. Why are these snippets put in
local.conf.sample.extended instead of separate, well-named .inc files
that can be shared by multiple distros? The current model seems to
encourage putting lots of configuration in local.conf that probably
should be in the distro or machine conf.

Try:
VIRTUAL-RUNTIME_initscripts = "systemd-compat-units"
Enabling systemd is somewhat documented by the example in
{meta-poky,openembedded-core/meta}/conf/local.conf.sample.extended,
which is:
#
# Use systemd for system initialization
#
# DISTRO_FEATURES_append = " systemd"
# DISTRO_FEATURES_BACKFILL_CONSIDERED += "sysvinit"
# VIRTUAL-RUNTIME_init_manager = "systemd"
# VIRTUAL-RUNTIME_initscripts = "systemd-compat-units"
