I did some tests. This issue is clearly related to btrfs, because I can not reproduce this with ext4. If you have a different filesystem, you have a different issue, maybe the one in https://launchpad.net/bugs/1804847.
How to reproduce this:
1) clean install from 'ubuntu-18.04.1-live-server-amd64.iso', all settings default but change root filesystem to btrfs.
2) system starts fine after reboot
3) issue 'apt install systemd' and get the 'Bad file descriptor' error allready during installation (attached log)
4) reboot with failing systemd-tmpfiles-setup.service
I will also attach a log of the errors during apt install.
