You do realize that RPM5 has the mongo-c-driver embedded inside, batteries included,
for the past 5 years?

Seriously: most rpm users have nearly identical configurations and the
days where each and every client PC need their own speshul copy
of changelogs and descriptions and identical blobs of header metadata
are clearly numbered.

Note that rpm5 has also embedded sqlite (i.e so that sql updates can be
distributed through %post, and so that multiple copies of installed software
metadata in schema-du-jour can be used as one wishes).

*shrug* My job is to make implementations exist, not honk my warez.

BDB has done an excellent job maintaining a consistent backward compatible API:
there is nothing whatsoever wrong with BDB 5.x as used by RPM.

Bundle BDB into RPM if you don’t want the added package monkey task maintaining
older versions of BDB as a package, license and batteries included.
