+Configure tries to figure out if the local system uses group "nobody" or
+"nogroup" by looking in the /etc/group file. (This is only used for the
+default group of an rsync daemon, which attempts to run with "nobody"
+user and group permissions.) You can change the default user and group
+for the daemon by editing the NOBODY_USER and NOBODY_GROUP defines in
+config.h, or just override them in your /etc/rsyncd.conf file.
