I tried to reply to Brian's question earlier but google-groups seems to have eaten it *eyeroll*. Here's what I wrote:
[In reply to being asked why I think using daemon(3) isn't great] Mostly that it's a function of the context, not the program, whether it is to be treated as a daemon or not. But there's also a bunch of stuff to do with whether the process is/should be a session leader or not, which is again something the program itself shouldn't be making decisions about. djb writes a bit about this topic here: https://cr.yp.to/daemontools/faq/create.html#fghack . The systemd people even seem to agree (calling a non-backgrounding daemon a "new-style daemon"), at least as far as non-backgrounding goes: http://0pointer.de/public/systemd-man/daemon.html#New-Style%20Daemons Cheers, Tony On Sat, 1 Dec 2018 at 23:12, George Neuner <gneun...@comcast.net> wrote: > On Thu, 29 Nov 2018 07:19:17 -0800 (PST), Brian Adkins > <lojicdot...@gmail.com> wrote: > > >Just out of curiosity, why do you feel using daemon(3) is not a great > idea? > >I'm not disagreeing, just curious about your reasons. > > > >On Thursday, November 29, 2018 at 5:54:42 AM UTC-5, Tony Garnock-Jones > >wrote: > >> > >> IMO using daemon(3) is not a great idea.
