+path, and leading slashes are removed from most absolute paths (options
+such as --backup-dir, --compare-dest, etc. interpret an absolute path as
+rooted in the module's "path" dir, just as if chroot was specified).
+The default for "use chroot" is true.
+
+In order to preserve usernames and groupnames, rsync needs to be able to
+use the standard library functions for looking up names and IDs (i.e.
+getpwuid(), getgrgid(), getpwname(), and getgrnam()). This means a
+process in the chroot namespace will need to have access to the resources
+used by these library functions (traditionally /etc/passwd and
+/etc/group). If these resources are not available, rsync will only be
+able to copy the IDs, just as if the --numeric-ids option had been
+specified.
+
+Note that you are free to setup user/group information in the chroot area
+differently from your normal system. For example, you could abbreviate
+the list of users and groups. Also, you can protect this information
+from being downloaded by adding an exclude rule to the rsync.conf file
+(e.g. "exclude = /etc/"). To protect it from being changed by an upload

specify the maximum number of simultaneous connections you will allow.

for modules to be listable.

file transfers to and from that module should take place as when the daemon
was run as root. In combination with the "gid" option this determines what
file permissions are available. The default is uid -2, which is normally
the user "nobody".

was run as root. This complements the "uid" option. The default is gid -2,
which is normally the group "nobody".

than the one that the rsync daemon is running under. If "strict modes" is
false, the check is not performed. The default is true. This option
was added to accommodate rsync running on the Windows operating system.
The default is no "hosts deny" option, which means all hosts can connect.

can ensure that rsync won't wait on a dead client forever. The timeout
