Partly.  Bu mainly because we need a new SAL error record section with
its own GUID and an agreed format.

You mentioned in another mail "Someone also raised the technical
question of whether the new format included enough information to
relate it to a particular processor, i.e., maybe it should include the
LID".  We already have the lid, in sal_log_processor_info.
