The dbopen(3) API can be provided on top of CDB, but it doesn't fit too
well with many of use cases e.g. in libc. The services(5) database is a
good example. There are multiple keys for entry and the db
implementation essentially emulated this by using an aritifical key for
the main entry and doing a double lookup for all keys. As the keys are
part of the data, the overall disk space usage is essentially doubled.
