I've just seen this email. I did see the failure from the overnight
build and already sent a reply suggesting how this can be fixed, it
should be a simple change.

The whole RFC was not merged. The previous RFC was and when that
happened, to avoid more rebuilds, I chose to merge some parts of the
second one since there appeared low risk.

I send out a lot of patches, in general I get zero replies to most of
them so its hard to know when I've waited "long enough". I did seek out
and talk to some people about those RFCs and the feedback was positive,
we all agree that the improvements to the dependency checking outweigh
any downsides, including to be this issue.

I think in this case the usage is rather horrid and not something I'd
say we've ever suggested or supported.

Should be as simple as s/populate_packages_prepend//. The
DEBIAN_NOAUTONAME doesn't really fit the description of the code there
FWIW, I know why you're doing it but its not what the comment says. 

I would not recommend setting variables in function prepends like this,
its ugly and error prone, as you've just found out.

Cheers,
