Is this enough to file a bug?
Eg:
"systemd-journalctl -f" fails to pass stdout file descriptor in such a
way that bash process substitution can work"
with the simple comparison example being, these work:
   colortail -f <(sudo tail -f /var/log/auth.log)
   colortail -f <(systemd-journalctl)
yet this does not work:
   colortail -f <(systemd-journalctl -f)
