Questions tagged [runit]

runit is a cross-platform Unix init scheme with service supervision, a replacement for sysvinit, and other init schemes.

runit is is an init replacement that runs on GNU/Linux, *BSD, MacOSX, Solaris, and can be ported to other Unix operating systems.

Its primary advantages over traditional init is service supervision (the ability to automatically restart daemons that have died), and reliable logging via pipes. In this regard it is similar to the utilities.

More information can be found at the runit homepage.

What's the point of using runit in combination with monit?

I see a lot of people using monit in combination with runit. Isn't that redundant? What is the point of using runit as well? Is it because it's more reliable when dealing with services (as it doesn't rely on pidfiles)? Thanks!
