Return to accesscount_seed.piml CVS log

- Avoid time-consuming recursion of user directories when running ./UPDATE
  to fix pre LON-CAPA 2.0 (and pre-2.2 in one case), which will have been
  fixed when library servers were updated to versions 2.2 through 2.10.
- No pre-2.2 instances currently in the production cluster.
