/bin/bash all the things. Since we are using bash syntax in some of the element fragments, we should make sure we use bash for all of them, so that things don't break on systems where /bin/sh != /bin/bash.

Disable Apt Recommends. This disables apt's default behaviour of installing packages in the Recommends field of other packages. While this can be useful, it causes a lot of unnecessary software to be installed and may cause explicit dependencies to be missed in some circumstances.

set -e all the things Using set -e in all of our scripts will prevent some subtle bugs from slipping in, and will allow us to enforce use of set -e with tooling. This change also adds -u and set -o pipefail in the less complex scripts where it is unlikely to cause problems. A follow-up change will enable those options in the complex scripts so that if it breaks something it can be reverted easily.
