The Epoch Init System is an init system for Linux designed with ease of configuration and non-intrusiveness in mind. It has no external dependencies besides libc and pthreads on a Linux 2.6+ system, though a working /bin/sh is suggested. It's suitable for large and small Linux distributions, but was designed with a focus on smaller Linux systems. It's features include a log system capable of recording boot events before the filesystem is made writable, ASCII runlevels, a convenient, single configuration file setup, automatic hostname setting at boot, automatic virtual filesystem mounting (think /proc), PID file support, stuck job killing during bootup and shutdown, integrated color greeting banner support, and automatic service restart support, to keep vital services running at all times.
pmtr starts your application daemons (not the system daemons) at system boot and lets you dynamically add, remove, or edit jobs at runtime. What makes pmtr different from sysvinit and similar systems is that all your jobs are defined in one configuration file, and the syntax is friendly.
