<para>If you want to do similar changes to your files, please do that only
if you're feeling comfortably with the concepts. Otherwise don't be surprised
if some stuff doesn't work anymore. If you screwed up things, revert to files
created by mkpasswd and mkgroup. Especially don't change the uid or the name
of user SYSTEM. Even if that works mostly, some Cygwin applications running
as local service under that account could behave strangly suddenly.</para>
