I'm on a ubuntu server, once I install supervisord will it start on reboots?
How can I find this out?
Check that you have a script /etc/init.d/supervisor or similar and that there are relevant symlinks in /etc/rc?.d. If not something like
should do the trick once you get a start script into /etc/init.d.
Having said that, if you install supervisor from a package and it didn't install and setup a start script, you are entitled to complain to the package maintainer.
You can use sysv-rc-conf for Ubuntu where Centos or similar might use chkconfig
if it isnt already installed
