Just like stdout, stderr is essential for programs that the user runs on
the remote machine. Please don't close it unless and until the user
does (e.g. ssh remote 'exec command 2>&-')

This seems really wrong. #1902 refers to #1988 as reason for not
chdir’ing to / but #1988 is about (1, 0) vs. (1, 1) whereas #1902
is about (0, 1) vs. (1, 1) so perhaps changing the daemon call to
(0, 0) will fix both?
bye,
//mirabilos, not (yet) having looked at that code, just wondering
Ah, #1988 is the reason. I would think that if that problem
was that stderr is left open, the solution is to close stderr
(when not debugging), rather than to not chdir /.
cheers,
raf
