Revert 1558dfbf3b2a42f43594acf6e3d8f9b329ff1133 and 984cbd4eb023001668eea530e2b5ed2e57ba3693 and depend on bash

There was no proper upgrade path for these changes. This can be reconsidered once a clean upgrade path is provided.
Compatibility with non-bash shells is not as important as backwards-compatibility of existing configurations.
