I am on CentOS 6.5 and about to add a service to the system with
chkconfig. It will run with its own system account, let's call it (the account)
foobar, but I do not see the point of also creating the
foobar group with it. I am contemplating making the account have
daemon as its primary login group, because it's a service. But before I do, I would really like to know what this
daemon group (and user!) are all about?
CentOS documentation just lists these in a table, without much additional information.
