The current WIP patch has the main Samba version string directly used
for ldb, therefore allowing ldb to change during a release stream (eg
for a security release).

Please look carefully at the MR for the details, I would certainly not
wish any more miscommunication!

Great!  I was sure we could find some common ground.

So from here we just need to know if this (eg) libldb-4.11 needs a
distinct tarball to be generated by the release team.  

Now that we are clear on what is being talked about, I have also re-
opened this:

 https://gitlab.com/samba-team/samba/merge_requests/371

If we decide not to burden the release team with a distinct tarball,
then distributors building ldb would just need to use the main samba
tarball and add a 'cd lib/ldb' to their build scripts. 

Finally, this is all just WIP proposals, other variations on this
approach are most welcome.  But if you do agree with any of the above
please mark that on the relevant MR so I can keep track.

Thank you very much for your thoughtful consideration of the above,

Andrew Bartlett
