I'm concerned that the necessary building tools for "compat-nettle32"
and "compat-gnutls" from Sergio are not apparent in that merge
request. I found those necessary because I disabled the "experimenta"
MIT KRB options, and gnutls is not recent enough on RHEL 7. Sergio
For my work, I also have a full build structure and a set of git
submodules with all the libtdb, libtalloc, libtevent, and libldb
libraries to build up for a full deployment: sergio used the "build
the libraries internally in Samba" option.

I'm not sure how to merge the work into the existing bootstrap
procedure, since they'd also expect these other modules to be built
and available in the bootstrap and yum deployment. Do these bootstrap
environment ssupport the use of "mock" ? I've also just noted that
mock, on RHEL 7, does not support "file://$PWD" syntax for finding the
local repository that my setup drops generated RPM's in. Works great
on Fedora, not on RHEL 7 or CentOS 7. That means the build environment
needs a web-based access to the built repository, which I'm doing with
"nginx", on RHEL 7. That.... makes it more awkward for an individual
software builder to be access their local working repositories. It can
be done stably, but it needs to be really locked down for a safe build
environment.
