[=E2=80=A6] The choice of =E2=80=98bash-static=E2=80=99 rather than =E2=80=98bash-minim= al=E2=80=99 is motivated by the fact that, in (gnu packages commencement), we want to make sure =E2=80=98glibc-final=E2=80=99 does not retain references to its build-time = environment. See #:allowed-references in =E2=80=98glibc-final=E2=80=99. > 2) If we want to make 'sh' a weak/dynamic reference, I think we should=20 > strongly consider arranging to make it available at '/bin/sh' when presen= t.

Overall, I think the current situation is a reasonable tradeoff. It forces us to do some patching, indeed, but I think that=E2=80=99s acceptabl= e: we=E2=80=99re talking about a handful of packages. WDYT? Ludo=E2=80=99.
