If I might interject for a moment, this was a major issue a few years ago
with Ubuntu: https://wiki.ubuntu.com/DashAsBinSh

Essentially, people were using Bash-isms without realizing it and starting
their shell scripts with /bin/sh.  In Debian, it is policy for all shell
scripts that specify /bin/sh should only use POSIX features.  So, for Ubuntu
changed the /bin/sh aliase to /bin/dash from /bin/bash.  Dash is a lot like
bash, but not quite.  This caused some... interesting... issues.

The link I provided above mentions some of the usual gotchas.  Whether they
apply to the issue at hand or not, I wouldn't know, but it has been a handy
reference for me before.

I'll go back to my hole...
