And, lo and behold, I'm on schedule for once.

s6-rc-0.0.1.0 is out.

s6-rc is a service manager for Unix systems, running on top of
a s6 supervision tree. It manages the live state of the machine,
defined by a set of services, by bringing those services up or
down as ordered by the user.

It handles long-lived processes, a.k.a. "longruns", ensuring they're
supervised by the s6 tree. It also handles one-time initialization
scripts, a.k.a. "oneshots", running them in a reproducible environment
without needing the usual sanitizer boilerplate.

It manages dependencies between services, no matter whether they are
oneshots or longruns; it can intertwine oneshot starts and longrun
starts, or oneshot stops and longrun stops. When changing the machine
state, it always ensures the consistency of the dependency graph.

Services can be grouped in collections named "bundles", for easier
manipulation. Bundles are like runlevels, but more powerful and
flexible.

s6-rc allows an arbitrary number of longrun services to be pipelined.
s6, and other supervision suites, can maintain a pipe between a
producer and a consumer ("logger"), so the producer or the consumer
can restart without breaking the pipe and losing any data; s6-rc
extends this idea to an arbitrary chain of producers piping their
data into consumers that themselves pipe their data into...

s6-rc features the shortest run-time code path of any service manager
to this day: this includes systemd, sysv-rc, and OpenRC.

Enjoy,
Bug-reports welcome.

Please send your reports and suggestions to the
skaware@??? mailing-list. (You can subscribe by sending
a mail to skaware-subscribe@???.) That is where s6-rc
is discussed, even if we can of course talk about a possible use in
Devuan here. Thanks!
