No, it wouldn't.

I thought testdata contained a filtered list of variable keys but it
doesn't, its a complete dump of the data store with some variables
"broken" by the removal of TOPDIR. My proposal was based on my thought
that it was filtered so that won't work.

It is not clearly broken. Its broken in the way you're trying to use it
and expect it to work.

The usage of testdata is alongside the image that is built, they're a
paired item. The image and the testdata go together. Either both are
rebuilt together or they're not.

Personally, I think testdata should get filtered to the list of
variables the testing code really needs, not just a dump of every
value.

I thought the tests had markup to indicate which variables they needed
for that reason, so a list of variables could be constructed. If we did
that, this would allow us to rewrite the file (and rebuild the rootfs)
when the values changed.

I would very much like to fix that and your other patches in this area
are good. Unfortunately you change a lot in the patches in one go
though and it was too difficult to review like that.

If you were able to split those into smaller pieces that make one
logical change/fix in each, that would help in getting those ones in at
least.

Improving the test coverage so that things don't get broken again would
also be very helpful.

Cheers,
