+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.
