systemd/systemd-228-nspawn-make-journal-linking-non-fatal-in-try-and-auto.diff
Dr. Werner Fink 9a374333da - require curl and bzip2 to build importd
- curl also causes building of journal-upload. That one has rather
  unusal certificate usage, set it's ca root to /etc/pki/systemd
  instead of the built-in default /etc/ssl as journal-remote and
  journal-upload think they kan put stuff in /etc/ssl/certs then but
  that directory is managed by p11-kit and doesn't serve the purpose
  those programs think.
- /var/lib/systemd/random-seed is a file
- own /var/lib/machines
