I mean that I package both bash and dash for cygwin, so it is fairly easy for me as packager to make the switch for all users of future cygwin downloads. What is less easy is getting agreement on cygwin-apps that it is the right time to make such a switch, as it may affect other packages that don't realize they are shipping with non-sh-compatible /bin/sh scripts (although thanks to Debian's efforts, this is a lot better now than it used to be). Don't worry, I wouldn't do it without a reasonable lead-up time for experimental testing and appropriate consensus. But there ARE benefits to switching /bin/sh to dash: as it loads fewer shared libraries and has less code bloat, it executes and forks a lot faster, and since forking is noticeably slow on cygwin, anything we can do to make non-interactive scripts faster is probably worth it. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
