systemd aborts and freezes execution during installation or uninstallation of IPA. The error occurs during ipa-client-install enrolment of the IdM master. After the abort, the system becomes unusable, e.g. systemctl status fails with "Failed to read server status: Connection timed out", reboot fails with "Failed to open /dev/initctl: No such device or address".
