Rename the database after closing it in hpropd
If a Berkeley DB database is used as the underlying database, renaming
the database before closing it can produce error messages like the
following on close:
/var/lib/heimdal-kdc/heimdal~.db: unable to flush: No such file or directory
since the underlying database library caches the old file name. There
is a rename() method in the Berkeley DB API, but it also invalidates
the database handle and requires that it be reopened. Since the
hdb_rename implementation does not require that the database be open,
close the database before renaming it to avoid this problem.
