Bug 681648

This will need backward compatibility support for LL_DAEMON in configuration

There is now an included example configuration file, but it needs human interaction before it can be used.

Also, configuration params have changed:
LL_BROKER -> CAROD_BROKER
LL_DAEMON -> CAROD

Older params are still accepted, with the exception of the tests.  Only the CAROD params are accepted in the tests.

Fixed on master

    Technical note added. If any revisions are required, please edit the "Technical Notes" field
    accordingly. All revisions will be proofread by the Engineering Content Services team.
    
    New Contents:
C: The switch to using LOCAL_CONFIG_DIR allows for ease in configuration of external features
C: There was no example configuration file that could be easily modified and dropped into LOCAL_CONFIG_DIR
C: An example configuration file is included in the condor-low-latency rpm
R: Configuration of Low-Latency is much easier

It seems that the old parameters (LL_*) are not working anymore, and this is not expected in a minor update.

Issue fixed in latest package in FiV

There is a new example of configuration file with CAROD_ parameters as part of low latency package. Older params are still accepted.

The change of subsystem name from LL_DAEMON to CAROD in the configuration is covered by bug 718348.

Tested with:
condor-low-latency-1.2-2

Tested on:
RHEL5 x86_64,i386
RHEL6 x86_64,i386
