Correct.

If you mean a custom taskomatic bunch/task, then no. We never intended
to let the user define custom taskomatic bunches/tasks.

The bunches are pre-defined and the user may just adjust, how often and
when they shall be scheduled.

You only can check what tasks get run within a bunch on the /rhn/admin/BunchDetail.do pages.

The compare config files task actually creates an action for every server with
attached configuration revisions to make a diff on the client side.

Is it possible that you lately increased number of managed configuration files per server?
