I'm not sure why you are making this observation.  The error that
Dennis is reporting is that he couldn't find /bin/sh.  The error
is coming *from* bash but there is no indication that he wants
/bin/bash to be copied to /bin/sh.

The solution is probably to rerun setup.exe and specifically select
'ash'.  If it seems to be installed, uninstall it and then reinstall it.

If that still doesn't solve the problem then 'cygcheck -r -s -v' output
will probably pinpoint the problem.

Indeed.  Please don't do this, or even recommend it unless you really
know what you're doing.  Suggesting that people with problems modify
their installation in a non-standard way is generally not good advice.
