Thanks! We also need to look at our samba package, which bundles heimdal
(we should fix that).

Okay.

> 2. A lots of libraries are bundled

Which directory are they in? We should take a look at them and weigh the
risk of adding new vulnerabilities through the use of (possibly old and
unmaintained) bundled libraries.

If things look complicated, maybe it's possible to apply a patch to this
older Heimdal while we figure everything out.

Maybe we can find a patch for CVE-2017-11103 from Red Hat or another
long-term-support distro. I noticed an unrelated patch for Heimdal
1.6 here:
https://anonscm.debian.org/cgit/collab-maint/heimdal.git/commit/?h=debian/jessie&id=6d27073da8b45b5c67ca4ad74696489e49c4df1a

> 3. Many db tests fail

Do you think they are a problem in practice? Ludovic, you added Heimdal,
what do you think about this big version bump?

> 4. It does not build reproducibly

Not great but also not a blocker.

Do we re-bootstrap because we edit Makefile.am? Is it possible to edit
the generated Makefile directly?
