kerl cleanup not actually running?

[jimsynz]

I notice that bin/install does actually call kerl cleanup after successful install, however I think it must be calling it with the incorrect environment or something because when I do a fresh install of Erlang 26.0.2 I have over 700MB of files sitting in .asdf/plugins/erlang/kerl-home/builds/asdf_26.0.2/otp_src_26.0.2.

You can reproduce it like so:

docker pull code.harton.nz/james/asdf_container:latest
docker run --rm -it code.harton.nz/james/asdf_container:latest
$ asdf plugin add erlang
$ asdf install erlang latest
$ du -shc .asdf/plugins/erlang/kerl-home/builds/asdf_26.0.2
738M	.asdf/plugins/erlang/kerl-home/builds/asdf_26.0.2
738M	total
$ KERL_BASE_DIR=.asdf/plugins/erlang/kerl-home .asdf/plugins/erlang/kerl cleanup asdf_26.0.2 
Cleaning up compilation products for asdf_26.0.2
Cleaned up compilation products for asdf_26.0.2 under .asdf/plugins/erlang/kerl-home/builds
$ du -shc .asdf/plugins/erlang/kerl-home/builds/asdf_26.0.2
du: cannot access '.asdf/plugins/erlang/kerl-home/builds/asdf_26.0.2': No such file or directory

Let me know if there's any way I can further help debug this.

I think I figured out the problem here. I will create a PR for this tomorrow.
