As elogind can not open any systemd journals, the functions sd_journal_open, sd_journal_open_directory, sd_journal_open_directory_fd, sd_journal_open_files, sd_journal_open_files_fd and sd_journal_close do nothing.
The sd_journal_open(), sd_journal_open_directory(), and sd_journal_open_files() calls return -ENOSYS.
sd_journal_close() returns nothing.
