Hello,

ng0 <ng0@n0.is> skribis:

I think shepherd could capture stdout/stderr of the processes it starts
and make it available, in a way similar in spirit to what ‘journalctl’
does.  That would allow you to see the output of the daemon that failed.

That’s the only solution I can think of.  Of course we don’t have to do
that if the daemon writes error messages to syslog, but not all of them do.

Thanks,
Ludo’.
