Daniel J. Bernstein's daemontools package, described by him as "a collection of tools for managing UNIX services", is the pioneer of what some people call today process supervision suites, i.e. packages that provide tools for performing process supervision  . There are no further releases of daemontools after 0.76, but other software packages have been inspired by its design principles, notably runit, s6, perp, nosh, and an enhanced succesor, daemontools-encore .

emerge --ask sys-process/daemontools
- /service - Location of the scan directory when using OpenRC or svscanboot.
See here for details.
emerge --ask --depclean sys-process/daemontools
The same extra steps after removing daemontools-encore apply here.
- runit — a daemontools-inspired process supervision suite that also provides a program suitable for running as process 1
- OpenRC — a dependency-based init system that maintains compatibility with the system provided init program
- systemd — a modern SysV-style init and rc replacement for Linux systems.
