What constitutes a configuration?
And please read my email subject. I can't have writable /etc, mender dosen't allow that.
In today's mobile computing age you really think users shouldn't change timezone?
You keep saying "
I for one am certainly not convinced that the timezones" but you don't explain why?
Are you looking at this system as a static machine? That can never change timezone?
And please don't use profanity. I have not and you shouldn't either.

Oh we do. But if your want configuration to be changable, then mount
/etc writable.
You have two contradicting goals: you want immutable config, but then
you want to change config. So how's that gonna work?
If you want your persistent config changable then make it changable,
i.e. mount /etc/ writable.

I explained this already. DNS server data today is much less config
than state, acquired dynamically via DHCP, hence most distros don#t
configure it in /etc so much anymore, but manage it in /run (where
transient state is generally kept), and only keep a compat symlink in
/etc. If you try to convince people though that the local timezone
should just be transient state and not persistent config you'll have a
hard time. I for one am certainly not convinced that the timezones are
state...
I mean, the line between persistent configuration and transient state
is blurry, but in the case of DNS settings and timezone settings I
certainly can draw a line easily.

We don't do that. Just make /etc/ writable ffs, if you want stuff in
/etc to be changable.
