+
+# For any daemon, you can specify a "wrap" command to start instead of starting
+# the daemon directly. This will simply be prepended to the daemon invocation.
+# These variables have the form daemon_wrap, where 'daemon' is the name of the
+# daemon (the same pattern as the daemon_options variables).
+#
+# Note that when daemons are started, they are told to daemonize with the `-d`
+# option. This has several implications. For one, the init script expects that
+# when it invokes a daemon, the invocation returns immediately. If you add a
+# wrap command here, it must comply with this expectation and daemonize as
+# well, or the init script will never return. Furthermore, because daemons are
+# themselves daemonized with -d, you must ensure that your wrapper command is
+# capable of following child processes after a fork() if you need it to do so.
+#
+# If your desired wrapper does not support daemonization, you can wrap it with
+# a utility program that daemonizes programs, such as 'daemonize'. An example
+# of this might look like:
+#
+# bgpd_wrap="/usr/bin/daemonize /usr/bin/mywrapper"
+#
+# This is particularly useful for programs which record processes but lack
+# daemonization options, such as perf and rr.
+#
+# If you wish to wrap all daemons in the same way, you may set the "all_wrap"
+# variable.
