As installed on my x86_64 system with documentation, it consumes around 576 *kilobytes* of storage space. It compiles and installs in substantially less than a minute. Learning how to craft s6-rc service definition directories is no more difficult than learning how to craft s6 servicedirs. - You don't lose any capability provided by s6 if you also use s6-rc. You can send whatever signals you want to the supervised processes by using s6-svc directly. So ... costs ~= 0, benefits > 0, to me the question of whether s6 is useful _without_ s6-rc is kind of pointless. I'm inclined to turn the question around: what leads you to want to avoid s6-rc? Is there some other system that provides more benefits at lower cost? Cheers! Brett -- Brett Neumeier (bneume...@gmail.com)
