We are pleased to announce the GNU Shepherd version 0.8.1.  This release
represents 49 commits by 3 people, bringing a new concurrent,
event-driven core, improved logging, and on-demand service startup.


• About

  The GNU Daemon Shepherd or GNU Shepherd is a service manager written
  in Guile that looks after the herd of system services.  It provides a
  replacement for the service-managing capabilities of SysV-init (or any
  other init) with a dependency-based system with a convenient
  interface.  The GNU Shepherd may also be used by unprivileged users to
  manage per-user daemons (e.g., tor, privoxy, mcron, etc.)  It is
  written in Guile Scheme, and is configured and extended using Guile.

  The GNU Shepherd is developed jointly with the GNU Guix project; it is
  used as the init system of Guix, GNU’s advanced GNU/Linux distribution.

Does Shepherd only run on Linux?

Thanks,

Hey,

from the README:

> POSIX-like system where Guile is available.  In particular, it has been
> tested on GNU/Linux.

So if you prefer to run the Hurd rather than Linux, it should work fine.

Vale,

Tim, thanks!

I run FreeBSD and it uses kqueue instead of epoll so even if Guile
technically runs on FreeBSD, fibers do not.

I don't mind submitting a patch to make this happen.

Some pointers you might find helpful:

When Ludo’ originally announced this work⁰, this limitation was known, 
but, fortunately, work is already underway to bring fibers to other 
platforms via libevent¹.

Should that not be $XDG_STATE_DIR?

	I believe it should be $XDG_STATE_HOME, in fact. See:
	https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html

---[snip]---
 $XDG_STATE_HOME defines the base directory relative to which
 user-specific state files should be stored. If $XDG_STATE_HOME is
 either not set or empty, a default equal to $HOME/.local/state should
 be used.
