Gnus/5.13 (Gnus v5.13) Emacs/28.2 (gnu/linux)
We are pleased to announce the GNU Shepherd version 0.10.2, a bug-fix
release of the new 0.10.x series, representing 28 commits over 7 weeks.
The 0.10.x series is a major overhaul towards 1.0, addressing shortcomings
and providing new features that help comprehend system state.
The GNU Shepherd is a service manager written in Guile that looks
after the herd of daemons running on the system. It can be used as an
“init” system (PID 1) and also by unprivileged users to manage
per-user daemons—e.g., tor, privoxy, mcron. It supports several
daemon startup mechanisms, including inetd and systemd-style socket
activation. The GNU Shepherd is configured in Guile Scheme and can be
extended in the same language. It builds on a simple memory-safe and
callback-free programming model.
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.
Here are the compressed sources and a GPG detached signature:

Here are the SHA1 and SHA256 checksums:
The SHA256 checksum is base64 encoded, instead of the
hexadecimal encoding that most checksum tools default to.
Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact. First, be sure to download both the .sig file
and the corresponding tarball. Then, run a command like this:
gpg --verify shepherd-0.10.2.tar.gz.sig
The signature should match the fingerprint of the following key:
pub rsa4096 2014-08-11 [SC]
3CE4 6455 8A84 FDC6 9DB4 0CFB 090B 1199 3D9A EBB5
uid [ full ] Ludovic Courtès <firstname.lastname@example.org>
uid [ full ] Ludovic Courtès <email@example.com>
uid [ full ] Ludovic Courtès (Inria) <firstname.lastname@example.org>
If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.
gpg --recv-keys 3CE464558A84FDC69DB40CFB090B11993D9AEBB5
As a last resort to find the key, you can try the official GNU
wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
gpg --keyring gnu-keyring.gpg --verify shepherd-0.10.2.tar.gz.sig
This release was bootstrapped with the following tools:
• Changes since version 0.10.1 (excerpt from the NEWS file)
** ‘shepherd’ loads configuration file asynchronously
Up to 0.10.1, ‘shepherd’ would load the user-provided configuration file
synchronously: it would write its PID file and start listening for incoming
connections only after the configuration file has been loaded. The
configuration file is now loaded in the background, letting users interact
with shepherd (using the ‘herd’ command) early on.
** ‘shepherd’ keeps going upon configuration file errors
Up to 0.10.1, ‘shepherd’ would abruptly exit when an error would occur while
loading the configuration file—service startup failure, uncaught exception,
etc. It now reports the error but keeps going, again letting users fix any
** New #:respawn-limit parameter to ‘service’
The ‘service’ form supports a new #:respawn-limit parameter to specify
per-service respawn limits.
** Disabled services are truly disabled
Previously, manually running ‘herd disable SERVICE’ would not prevent SERVICE
from being respawned or even from being started. This is now fixed.
** Disabled flag is preserved when replacing a service
When replacing a service, for instance by running ‘herd load root conf.scm’ or
by running ‘guix system reconfigure’, the service replacement starts as
disabled if the original service was disabled.
** Signals are properly handled after ‘daemonize’
Starting with version 0.9.0, calling the ‘daemonize’ action on the ‘root’
service would cause shepherd to miss signals; in particular, it would miss
SIGCHLD signals, making it hardly usable. This is now fixed.
** New ‘unregister-services’ procedure
The (shepherd service) module now exports ‘unregister-services’.
** New Bash completion
A Bash completion file is now installed, providing tab completion for the
** ‘herd’ shows a hint when the service and action are likely swapped
The hint is printed for instance when typing ‘herd foobar start’.
** Updated translations: de, ro, sv, uk
This release is fully translated to German, Romanian, Swedish, and Ukrainian;
partial translations are available for a dozen of languages. To help make the
Shepherd speak your language, check out the Translation Project:
