Some stuff is listed in the README file (REQUIREMENTS and WARNINGS
sections), but it doesn't really covers all possible misconfigurations,
of course.

To figure out what exactly goes wrong, I think it might help to disable
pymouth, remove "quiet" from kernel cmdline and add somehing like
"systemd.log_level=debug systemd.log_target=kmsg" there (see systemd(1)
and kernel Documentation on cmdline parameters).
