mlocate is a locate/updatedb implementation. It keeps a database of
all existing files and allows you to lookup files by name.
The 'm' stands for "merging": updatedb reuses the existing database to avoid
rereading most of the file system, which makes updatedb faster and does not
trash the system caches as much as traditional locate implementations.

- mlocate.db is ghost file created with non-default attrs, list them explicitly so rpm --verify doesn't report errors (#1182304)
