Building RPM in LFS 12.2
========================

This git is for the scripts needed to build the dependencies for the RPM Package
Manager (RPM) within a LFS 12.2 system. This is ‘Phase Three’ in `THE-PLAN.md`.

First I am attempting to build RPM 4.18.x as I successfully built that version
of RPM on LFS 11.3. However that version of RPM is EOL so once I get it building
I will not install it but instead look to see if I can the modern version of RPM
to build. I believe they changed the build system to CMake so there will almost
be some additional dependencies needed.

With dependencies through Lua built, RPM 4.18.2 builds in LFS 12.2 but there are
still three needed components for a complete RPM environment:

1. GnuPG (critical, needed to sign packages, important for package security)
2. debugedit (critical, needed for debug packages)
3. fakechroot (needed to run the test suite after building RPM)

GnuPG itself has a lot of dependencies, one of which is OpenLDAP. Hopefully I
can just build the shared libraries, those should be all that are needed.

While not a *strict* dependency, GnuTLS is a recommended dependency as is
pinentry but pinentry seems to be runtime so I probably will not build that at
least not until the RPM bootstrap is complete.

GnuTLS however will be used for *many* other things too, so I will consider it
and its dependencies as needed in this phase.
