runit

Purpose: runit is a cross-platform Unix init scheme with service supervision and a replacement for sysvinit and other init schemes.
Operating systems: The maker says runit runs on GNU/Linux, *BSD, MacOSX and Solaris, and can be adapted to other Unix operating systems.
Boot lifecycle: As process 1, runit handles booting, normal operation and shutdown in three stages.
Service recovery: runsv starts a service's run program and restarts it if it exits, with an optional finish program and log service.
Service control: The sv program reports service status and supports commands to start, stop, restart, pause and signal supervised services.
Logging: svlogd reads log data, can filter messages and writes to automatically rotated logs.
Process limits: The chpst utility can change process state and set limits including memory, open files, process count, output size, core size and CPU time.
Service capacity: runsvdir starts and monitors runsv processes for up to 1,000 service subdirectories.
Installation: The maker provides a source archive and instructions to compile and install runit, including manual installation without root access.
Optional init replacement: The maker documents using runit's service supervision alongside a system's current init scheme without replacing it.
Distribution availability: The maker lists Debian, FreeBSD, OpenBSD, NetBSD, Ubuntu, Gentoo, Arch Linux, Void Linux and other distributions as including or packaging runit.
Support channel: The maker directs runit discussion to the supervision mailing list and asks users to contact the list rather than the author privately.
Reliability and size: The maker says runit is optimized for reliability and small size, with minimal code in process 1.
Log transport limit: svlogd documentation warns that UDP logging is unreliable and should be used only in private networks.
