If user really wants to, they can set it in /etc/syslog.conf. +Moved pawd's path-matching functionality into Amd, where it can be done a +lot more efficiently (we no longer need to construct and send the whole +mounted tree, only to match small parts of it). This will lessen the CPU +and network load on systems that use pawd heavily, and also minimize the +chance that we exceed default or hard-coded UDP/TCP RPC packet sizes. + +Changed slightly how Amd behaves when you try to change log_options after +Amd started (options can be turned on/off via "amq -x ARG"). It used to be +that Amd won't let you turn off options which were on when Amd started. +That limited users' ability to reduce Amd's logging levels to a minimum. +Now, Amd will allow you to turn on/off any option, other than the two +options "fatal" and "error." Both are on by default and considered +mandatory. These two don't produce a lot of log messages, so your logs will +remain small, but they are important to keep on, so Amd can report serious +problems (including errors relating to incorrectly setting other log +options). + +Amd now understands a new log_option called "defaults" which is synonymous +with "fatal,error,user,warning,info" (and is also what logging happens by +default). + +Amd now understands a new debug_option called "defaults" which is synonymous +with "all,nohrtime,nomtab,noxdrtrace". + +Changed the misleading inverted logic of certain debug_options: + +1. "xdrtrace" is included in "all" because "all" (as the name implies), + should be *all* options, not just a subset. If you want the old behavior + of "all" then use "defaults" (all only adds "xdrtrace" which can be + chatty on some systems). + +2. Certain debug options are hereby declared immutable: they may not be + changed by "amq -D" after Amd starts, because it doesn't make much sense + to change them after Amd starts, and it could really mess up Amd. These + immutable flags are currently "daemon," "fork," "amq," and "mtab." + +3. the debug option "daemon" *will* cause Amd to daemonize. Before, it was + causing Amd NOT to daemonize. This was greatly confusing, especially + since the code, documentation, and comments often conflicted with each + other. If you don't want Amd to daemonize, which is useful for debugging + it, then use the debug option "nodaemon" -- it makes a lot more sense. + +4. Similarly, the "fork" option *will* cause Hlfsd to fork. Use "nofork" if + you don't want Hlfsd to fork. This option is only applicable to Hlfsd. + +5. Similarly, the "amq" option, which is now on by default, will cause Amd + to register itself with the RPC portmapper (for Amq), as is done + normally. If you don't want Amd to register with the portmapper, use + "noamq" -- this naming convention makes more sense. This was also + confusingly documented and coded in places. + + Note: unfortunately, these changes to the "daemon," "fork," and "amq" + debug options may be incompatible with people's previous use of Amd. + Some of you may have to update your amd.conf slightly or your startup + options (if they're hard-coded in your amd startup script).
