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 ^ permalink raw reply [flat|nested] 3+ messages in thread
