[07:39] <dennisdennis> I'm having an issue daemonizing a process, I'm using daemon from /etc/init.d/functions, but when I run service servicename start it just stays in the foreground.  Thoughts on what I should do?
[07:39] <dennisdennis> prometheus node_exporter for what it's worth
[08:00] <lnykryn> dennisdennis: deamon function from initscript does not daemonizy the process, it expect that the process will do classic double-fork
[08:02] <dennisdennis> does start-stop-daemon make the same assumption, I noticed that seems more like a Canonical thing, I'm on centos6 I suspect I can use Upstart, or maybe I can just do $ nohup /path/elf 2>&1 > logfile &
[08:02] <dennisdennis> What's the advantage of a service not double forking anyway and leaving the exercise up to the user??
[08:04] <lnykryn> dennisdennis: well I would guess that it is useful only in the case you want to run it from a different service and get notification if it dies
[08:05] <dennisdennis> as in you want it to be a child of something?  Is this a consideration for running the service in a container, that it should not double fork?
[08:05] <dennisdennis> or it doesn't really need to
[08:07] <lnykryn> this is really a difference for the sysvinit word, for new inits like upstart or systemd, there is a small difference
[08:10] <lnykryn> for example in systemd, the double forking service has the advantage that with end of the original process it can say "now I am running", service without doublefork is considered running immediately after the original command is run
[08:12] <lnykryn> in sysvinit world the double fork also allows to clean execution envioment for the final process
[08:19] <dennisdennis> I understand the distinction, thanks for your help
