Bjørn, All,

On 2014-10-21 16:05 +0200, Bjørn Forsman spake thusly:
> Not all systems have /bin/bash (e.g. NixOS[1] doesn't). Buildroot
> already uses /usr/bin/env shebangs for other interpreters (perl,
> python), so why not bash?
> 
> This changes only the shebangs used by Buildroot itself; stuff installed
> to the target system is left unchanged.
> 
> With this applied I can run Buildroot unmodified on NixOS.
