My issues concern porting a Linux application to cygwin. I read

resource I should read, please advise.
The application is "dnrd," published on SourceForge For security
reasons, dnrd
1. Insists that its config files be owned by root.
2. Changes its uid to "nobody," using setuid().

For the file ownership issue, I just have to decide if the appropriate
owner is SYSTEM, Administrator, or something else. And what about group
ownership?
$ cat /etc/group | grep root
root:S-1-5-32-544:0:
Someone inserted this into my /etc/group file.
For the uid issue, I might have to create an unprivileged account to
take the place of "nobody." Unless a more clever solution has been
worked out. Also, setuid() always fails for me. Are there limitations
to this function in cygwin?
Yes, this is covered in the User Guide:
