When we try to exec a new process image, this might fail for a number of reason (e.g. executable not found or not executable). As a result, the current process continues and
Process.execraises an appropriate exception. This exception can be caught somewhere and we should avoid any changes intended for the new process image to permanently affect the current process' environment.Using
Dir.cdwith a block ensures the directory is reset at the end of the block.Follow-up #16369
