GitLab is used only for code review, issue tracking and project management. Canonical locations for source code are still https://gitweb.torproject.org/ https://git.torproject.org/ and git-rw.torproject.org.
In #28113 (moved), we discovered that libsystemd-devel was not installed in travis. We should install it, and build with it.
We should probably do #28377 (moved) at the same time.
