updating rebar3 (wip/rebar3), erlang help?

[Nikita Gillmann <nikita%n0.is@localhost>]

Hi,

I'm trying to update rebar3 for wip/gleam.

I can't figure out where the build process of rebar3 makes a call to
update bbmustache from hex.pm.

When I comment the "false" match condition of fetch/2 in line 86 of
bootstrap, or when I leave it uncommented and add a print statement I
see that it's not in fetch itself.

I'm new to debugging Erlang code, so any help is appreciated.

I can't apply what Nix does in nixpkgs, they seem to manage to skip this
with a more complicated bootstrap including a self-written bootstrap
script for the bootstrap.
