Rebuilding operational schema

Is there any danger in running a database repair with the "Rebuild
Operational Schema" option selected? I see this as a solution in a
number of DSREPAIR errors, but I want to know if it is something that
can be run with a "normal" level of care, or if it's something that has
more impact than more typical db repair functions.

Is there any additional level of concern with rebuilding the operational
schema on the root partition?

I guess the underlying question is, what's going on in a rebuild of the
operational schema, and what concerns could there be with performing
this operation?

Thanks,
