when savedefconfig decides what to write out, what does it do for things

dependancy resolution?

The short version:
Any symbol that does not have default value are written to
the defconfig file.

Using the defconfig file as input or using the full config file
as input shall result in the same configuration.
If not you found a bug we need to fix.

Ok, so I take this to mean that if selecting one symbol forces selection of another, then both symbols will be written to the defconfig file, even though only the first would be needed to recreate the full file.

this is a wonderful step forward, I'm just trying to understand the nuances of it.

Arve found one bug I have to look into - pending feedback.
And I have found one bug related to tristate choice values.

So a bit work is needed to make it ready :-(
But it works for most of the defconfig we have today.
