Humm... Thanks for the point.
load_config -> lp_load -> pm_process -> do_parameter
do_parameter compares "motd file", like a key, then assigned
Globals.motd_file = "/etc/rsync.motd"
Well, NOW, take a close look at motd file, I know, it's something like
welcome message.
And the rsync protocol 30 only support 1024 chars of welcome message.
Thanks :)
