It took me a while to figure out why you were doing this.

We can't expand the data half way through loading the json file as
other pieces of data may later override the values. We therefore have
to defer expansion of variables until the file is completely loaded.

We therefore have to expand the variables later on, when we read them.

I pointed you at this commit:

http://git.yoctoproject.org/cgit/cgit.cgi/yocto-autobuilder-helper/commit/?id=d6253df2bc21752bc0b53202e491140b0994ff63

which changes direct accesses into ourconfig, e.g.:

ourconfig["REPO_STASH_DIR"]

into accesses using a function:

utils.getconfig("REPO_STASH_DIR", ourconfig)

and that function handles the expansion.

You should therefore be able to fix the clobberdir issue by using the
getconfig() method instead of direct access?

Cheers,

Richard
