Odd,

# (unset DISPLAY; su - nobody -c emacs)
No directory, logging in with HOME=/
emacs: Could not open file: /dev/tty

doesn't work anymore. One needs two steps,

# (unset DISPLAY; su - nobody)
No directory, logging in with HOME=/
nobody@jidanni2:/$ emacs

Also one can test with su nobody with no -.

$ apt-cache policy emacs-snapshot

I can't reproduce the recipe easily since the user nobody has no
password on my machine.

Is this a bug in Emacs though?  To me, it seems more like some quirk
of how su works in this case.  Does the above work with other
programs, for example "top" or something?

Best regards,
Stefan Kangas

OK I'll close this as it is not a common use case.
