Previously, startup and build scripts needed to include a "hashbang" statement, e.g.:
echo "foo" > /home/nt-user/workspace
Everyone (including us!) forgot to add the hashbang almost all the time, so we checked how these features were currently being used, and turned out 99.98% of the time, these were just Bash scripts anyway.
As such, these scripts are now always run with Bash. Any content that previously didn't use Bash has been updated to do so.
