Personally, I would invoke a variation of Linus's attitude to breaking user space apps: the distribution should not break existing user's scripts, even if they are not following "the rules".
If you want to speed up the scripts distributed by Cygwin, then I would suggest modifying those scripts to use #!/bin/dash. Or give the user an option to change "/bin/sh" to point to dash, but don't make that the default setting. But breaking who-knows-how-many user scripts without the user's informed consent seems like an undesirable solution. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
