Well, this sounds like an ad for systemd:
since it is hard to get writing daemons right, we have tought systemd a
lot of tricks so that what you need to do for proper daemonizations is
near to zero. systemd can do a lot of stuff for you, the forking, the
supervising, the dropping of privs, the setting up of a clean working
environment and more. Also, PID files are unnecessary with systemd. In
effect writing a daemon becomes very easy then, because the environment
will be set up completely for you right-away.
