These high-level flow diagrams map out the current (pre-6.6.0) logic of simp-rake-helpers ISO builds, with annotations relevant to the two major build updates for 6.6.0: “slim” mirrors of modular DNF repos and JMG’s restructure to support multiple OSes.
The diagrams.net source for the diagrams is embedded in each PNG file.
build:auto
The build:auto task is the starting point for development and release builds.
iso:build
The iso:build task is usually executed near the end of build:auto. It can also be run on its own.

build:yum:sync
The build:yum:sync task is executed by build:auto, prior to iso:build. It can also be run on its own.
pkg:checksig
The pkg:checksig task is executed by iso:build, just prior to pkg:repoclosure. It is not available as a public rake task.

Note (because it’s not obvious): I thought pkg:checksig's args might need an update to take multiple paths in rpm_dir (in order to accommodate JMG’s multiple OS/external repos work). However, the task internally glob-expands rpm_dir (into rpm_dirs), so it’s already possible to pass in multiple directories—although the string might end up looking extra weird.
Two drawbacks are worth mentioning:
If the paths are very different and don’t wildcard well, it will be necessary to use literal brace expansion (ex:
{p,q}) instead.But since it’s an argument for a Rake task, the commas in a brace expansion won’t work from the command line without some additional quote/escape ugliness.
From the command line (needs the quotes and escaped comma):
pkg:checksig['/path/to/{dir1/sub1\,dir2/sub2}']
rake-helpers style Ruby code just needs quotes:
Rake::Task["pkg:checksig"].invoke('/path/to/{dir1/sub1,dir2/sub2}')
If we split out the repos into the different directories JMG’s been working on, the brace expansion might look something like this:
Rake::Task["pkg:checksig"].invoke('/path/to/rpm_dirs/{SIMP,puppet,postgresql96,epel8}','/path/to/key_dir')
pkg:repoclosure 
The pkg:repoclosure task is executed by iso:build, just after pkg:checksig.

@Conan-Kudo I was thinking about making it more consistent with the rest of dnf and (for me) more straightforward -
lookaside repos are specified explicitly (not implicitly as a difference of sets --repoid - --check ).
Using --repoid in other dnf commands means you want to work only with these specific repos. Here the actual work was done on --check repos.
