There is an error in the ypserv build that prevents
successful updates of a slave NIS server from the master,
only leaving the intermediate map files (<mapname>~.db) on
This issue is mentioned in the README and BUGS files that
come with the ypserv source, but the solution is not
implemented in the spec file for the package. I emailed
the author and he confirmed this. Time for a rebuild...
BTW, the fix is to delete the --with-ndbm=yes flag and recompile
this is fixed in the errata release....
