You are correct.  I was repeating advice I had seen many times, which
advice appears to be wrong.  Looking at the source code for RPM, I think
that it tries to open the database, creating it if it is absent.  Running
"rpm -vv --initdb --dbpath /my/saved/database" only mentions opening the
Packages file, which was left untouched.  Doing "rpm -vv --verifydb"
mentions each database file, so I think that --initdb must be opening only
the Packages file, and not removing any files.
