 off, rsync can even be tricked into showing or changing data that is
 outside the module's path (as access-permissions allow).
 .IP
 The way rsync disables the use of symlinks is to prefix each one with the
 string "/rsyncd-munged/".  This prevents the links from being used as long
 as that directory does not exist.  When this parameter is enabled, rsync
 will refuse to run if that path is a directory or a symlink to a directory.
 When using the "munge symlinks" parameter in a chroot area that has an
 inside-chroot path of "/", you should add "/rsyncd-munged/" to the exclude
 setting for the module so that a user can't try to create it.
 .IP
 Note:  rsync makes no attempt to verify that any pre-existing symlinks in
 the module's hierarchy are as safe as you want them to be (unless, of
 course, it just copied in the whole hierarchy).  If you setup an rsync  course, it just copied in the whole hierarchy).  If you setup an rsync

 When set to True, this parameter tells the rsync daemon to open files with

 (on systems that support it) to avoid changing the access time of the files
 that are being transferred.  If your OS does not support the O_NOATIME flag
 then rsync will silently ignore this option.  Note also that some
 filesystems are mounted to avoid updating the atime on read access even

 .IP "\fBdont\ compress\fP"
 This parameter allows you to select filenames based on wildcard patterns
 that should not be compressed when pulling files from the daemon (no
 analogous parameter exists to govern the pushing of files to a daemon).
 Compression can be expensive in terms of CPU usage, so it is usually good
 to not try to compress files that won't compress well, such as already
 compressed files.
 .IP
 The "dont compress" parameter takes a space-separated list of
 case-insensitive wildcard patterns. Any source filename matching one of the
 patterns will be compressed as little as possible during the transfer.  If
 the compression algorithm has an "off" level (such as zlib/zlibx) then no
 compression occurs for those files.  Other algorithms have the level
 minimized to reduces the CPU usage as much as possible.
 .IP
 See the \fB\-\-skip-compress\fP parameter in the \fBrsync\fP(1) manpage for the
 list of file suffixes that are not compressed by default.  Specifying a
 value for the "dont compress" parameter changes the default when the daemon
 is the sender.
 .IP "\fBearly\ exec\fP, \fBpre-xfer\ exec\fP, \fBpost-xfer\ exec\fP"
 You may specify a command to be run in the early stages of the connection,
 or right before and/or after the transfer.  If the \fBearly\ exec\fP or
 \fBpre-xfer\ exec\fP command returns an error code, the transfer is aborted
 before it begins.  Any output from the \fBpre-xfer\ exec\fP command on stdout
 (up to several KB) will be displayed to the user when aborting, but is
 \fInot\fP displayed if the script returns success.  The other programs cannot
 send any text to the user.  All output except for the \fBpre-xfer\ exec\fP
 stdout goes to the corresponding daemon's stdout/stderr, which is typically
 discarded.  See the \fB\-\-no-detatch\fP option for a way to see the daemon's
 output, which can assist with debugging.
 .IP
 Note that the \fBearly\ exec\fP command runs before any part of the transfer
 request is known except for the module name.  This helper script can be
 used to setup a disk mount or decrypt some data into a module dir, but you
 may need to use \fBlock\ file\fP and \fBmax\ connections\fP to avoid concurrency
 issues.  If the client rsync specified the \fB\-\-early-input=FILE\fP option, it
 can send up to about 5K of data to the stdin of the early script.  The
 stdin will otherwise be empty.
 .IP
 Note that the \fBpost-xfer\ exec\fP command is still run even if one of the
 other scripts returns an error code. The \fBpre-xfer\ exec\fP command will \fInot\fP
 be run, however, if the \fBearly\ exec\fP command fails.
