Hello Gabriel,
bash is marked 'Essential: yes' so according to Debian policy, packages
ust not add dependencies on bash.
See policy 3.5:
Packages are not required to declare any dependencies they have on
other packages which are marked `Essential' (see below), and should
not do so unless they depend on a particular version of that
package.[1]
And 10.4:
If a shell script requires non-SUSv3 features from the shell
interpreter other than those listed above, the appropriate shell must
be specified in the first line of the script (e.g., `#!/bin/bash') and
the package must depend on the package providing the shell (unless the
shell package is marked "Essential", as in the case of `bash').
In this instance, bash is required because I do not know how to implement
the equivalent of '-o pipefail' with a POSIX shell.
