Hi Ingo Thank you for your reply.
I can't say I disagree with your and the OpenBSD team's attitude about bug-free daemons. But I am just a lowly application programmer, and sometimes I introduce horrible bugs that make our systems crash. In many cases it will be preferable to just start the process again (and, of course, fix the bug) for the purposes of keeping our business running. But another use for daemon(8) is for its ability to detach the child process from the controlling terminal and furthermore redirect its stdout/stderr to syslog. Is there some mechanism to do that from the shell? Perhaps a combination of nohup and starting a background job?
