daemontools is the "seminal process supervision toolkit" written by Daniel J. Bernstein as an improvement to the inittab, /etc/ttys, init.d or rc.local alternatives, providingall of the following features. Easy service installation and removal Easy first-time service startup Reliable restarts Easy, reliable signalling Clean process state PortabilityDue to lack of ongoing maintenance for daemontools, newer tools such as runit have subsequently been preferred by some.
