I just realized that this is hard, if not impossible to automate. Consider that an update to Cygwin 1.7.33 leaves /etc/passwd intact and no /etc/nsswitch.conf file will be installed. Thus, the default setting of "passwd: files db" will be used. Thus, the usernames won't change. They *might* change if the administrator of the system decides to remove /etc/passwd or set "passwd: db" in /etc/nsswitch.conf, but there's no way to anticipate this move in a postinstall script. The easiest thing to do would probbaly be to provide a conversion script for manual usage.
