mod_logfile and mod_syslog have uuid params which allow the logging of the uuid that generated a log message, if available.

mod_console and fs_cli do not have this feature, but it could be useful.

The attach patches add this feature. It is disabled by default, so that the default behaviour is unchanged. When the uuid param is set on mod_console, or the -U/--log-uuid command line argument given to fs_cli, the log message is prefixed by the uuid (the same behaviour as mod_logfile and mod_syslog).

fs_cli could be patched further so that the log-uuid setting is stored within profiles.
logger.pl also could be updated to show uuids (patch not supplied)
