The bogus root user should nevertheless have a real SID (and a UID of 0).
I suggest copying the SYSTEM entry and changing the username to root and
UID to 0 and making sure it appears before the real SYSTEM entry in
/etc/passwd (note that this may present problems with some apps, notably
apache, that hardcode the SYSTEM UID as 18 on Cygwin).
