I am glad that you have set out to implement this idea.
However, I am not convinced that you are implementing it
exactly the right way. The /etc/volatile.conf file looks
like overdesign to me. I don't see the need for the path
to /whatever to be configurable by the user. Shouldn't we
just decide on a path (e.g., /etc/run) and then move the
run-time state files there by patching programs? Symlinks
can be used to ease the transition.
Anyway, I've taken a look at your patch. Here are some

Doesn't allow for comments in /etc/volatile.conf.

Comment is unneeded and is possibly wrong

Case blocks are usually terminated with ';;'. I'm not sure
what you mean by a "real" fs. Could you be more explicit

Instead of copying large blocks of code, I suggest you
write a function or two.

I have read the whole thread and I don't recall reading
anything that explained why a skeleton directory is
needed. Presumably it is a kluge for backward compatibility.
If so, then this should be mentioned.
Also mention that you empty $volatile_mnt before filling
it with the contents of /etc/volatile-skel/.

I don't think that this discussion has been a flamewar.
I haven't seen many personal attacks. It's been a good
discussion of many different possible solutions to a problem
