This adds an explicit generation of md5-metadata cache before any we
do any emerge invocations. That way we can have a copy of reports even
if emerge fails for some reason. But mostly the reason for this
copying is to consume the data later, outside the SDK container.
The coreos-devel/sdk-depends is a metapackage that is emerged in
stage4 of the catalyst SDK build. But the fsscript that is being run
at the end of the stage4 build also pulls in dev-lang/rust package.
Thus pull both packages for the report.
This should result in updated dev-lang/rust to appear in the reports.
This adds some scripts I have been using for over a year to deal with
the weekly package updates.
It comes with a `README.md` which describes a workflow similar to my
own.
The `sync_packages.sh` and `update_packages.sh` scripts are currently
not used anywhere. The idea behind them was to use them for Github
Action, but that will come as a follow-up PR.
