+      Fac is a general-purpose build system inspired by make that utilizes
+      ptrace to ensure that all dependences are enumerated and that all
+      source files are added to a (git) repo. An important feature of fac
+      is that it automatically handles dependencies, rather than either
+      complaining about them or giving an incorrect build. Currently, fac
+      only runs on linux systems, but on those systems it is incredibly
+      easy to use!

+Subject: [PATCH 1/2] No impure bin sh
+
+default_shell is used to populuate default shell used to execute jobs.
+Unless SHELL is set to a different value this would be /bin/sh.
+Our stdenv provides sh in form of bash anyway. Having this value not
+hard-coded has some advantages:
+
+- It would ensure that on all systems it uses sh from its PATH rather
+  than /bin/sh, which helps as different systems might have different
+  shells there (bash vs. dash)
+- In the past I had issues with LD_PRELOAD with BEAR, where /bin/sh
+  used a different glibc than BEAR which came from my development shell.

-%%% ---------------------------------------------------------------------------
-%%% @doc
-%%% The purpose of this command is to prepare a rebar3 project so that
-%%% rebar3 understands that the dependencies are all already
-%%% installed. If you want a hygienic build on nix then you must run
-%%% this command before running rebar3. I suggest that you add a
-%%% `Makefile` to your project and have the bootstrap command be a
-%%% dependency of the build commands. See the nix documentation for
-%%% more information.
-%%%
-%%% This command designed to have as few dependencies as possible so
-%%% that it can be a dependency of root level packages like rebar3. To
-%%% that end it does many things in a fairly simplistic way. That is
-%%% by design.
-%%%
-%%% ### Assumptions
-%%%
-%%% This command makes the following assumptions:
-%%%
-%%% * It is run in a nix-shell or nix-build environment
-%%% * that all dependencies have been added to the ERL_LIBS
-%%%   Environment Variable
