It is the expected behavior if your /usr/share/info/DIR file doesn't
mention the Emacs manual.  Which probably means no one run the
'install-info' command when the Emacs manuals were installed on your
system.  "M-x info-emacs-manual" loads the Emacs Info manual directly,
bypassing the DIR menu, so it does work as soon as the manual is
available on your system.

Bottom line, you should investigate what is the source of the DIR file
and how it is updated when you install manuals.
