...except done _outside_ of Debian, so more comparative to (and no doubt 
far more elegantly written than) my scripts for https://bix.redpill.dk/ 
which is tracked at https://salsa.debian.org/tinker-team/box - to goal 
of those scripts is to be assimilated into Boxer, i.e. become a Debian 
_Pure_ Blend.

What format is that? Looks like a custom format to me.

I recommend using a common format, like ini (separating sections with 
[foo] lines instead of horisontal space being significant) or YAML or 
TOML or JSON or shell sourcable variables (i.e. the format used for 
/etc/default/* files so probably well-defined womewhere for that use).

Not sure, but I think YAML is commonly used nowadays. Boxer currently 
rely on "reclass" which was written for Puppet, Salt, and Ansible.

Yes, multistrap uses ini format.

Also, multistrap is only really a competitor for debootstrap, not an 
orchestration tool.
