To select bash, you would have to replicate the:

        depends on BR2_PACKAGE_BUSYBOX_SHOW_OTHERS

dependency of bash to cups-filters, which is a bit annoying, as it's
off by default.

Are the scripts that use #!/bin/bash really using bashims, or are they
using #!/bin/bash but are in fact POSIX compliant ?

Or could we install them only if bash is available ? Are they useful in
all situations, or only in some specific cases.

I'm just trying to figure out what is the right solution for this.
Perhaps ultimately the solution will be to select bash, with "depends
on BR2_PACKAGE_BUSYBOX_SHOW_OTHERS", but I'd like to explore the other
possibilities.

Thanks!

Thomas
