=E2=80=A2 About

  The 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
  =E2=80=9Cinit=E2=80=9D system (PID 1) and also by unprivileged users to m=
anage
  per-user daemons=E2=80=94e.g., gpg-agent, tor, privoxy.  It supports seve=
ral
  daemon startup mechanisms, including inetd, systemd-style socket
  activation, and timers.  The 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 Shepherd is developed jointly with the Guix project; it is used as
  the init system of Guix System and service manager of Guix Home.

  As a last resort to find the key, you can try the official GNU
  keyring:

    wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
    gpg --keyring gnu-keyring.gpg --verify shepherd-1.0.2.tar.gz.sig

  This tarball was bootstrapped with the following tools:
    Autoconf 2.71
    Automake 1.16.5
    Gettext 0.21
    Makeinfo 7.1.1

  It is bit-for-bit reproducible from a checkout of the =E2=80=98v1.0.2=E2=
=80=99 tag of
  the Git repository.

=E2=80=A2 Changes since version 1.0.1

  ** =E2=80=98daemonize=E2=80=99 action preserves replacement bindings for =
=E2=80=98sleep=E2=80=99 etc.
     (<https://issues.guix.gnu.org/75460>)

  The shepherd process replaces bindings for =E2=80=98sleep=E2=80=99, =E2=
=80=98system*=E2=80=99, =E2=80=98system=E2=80=99, and
  other core Guile procedures with cooperative variants thereof=E2=80=94for=
 instance, it
  replaces =E2=80=98sleep=E2=80=99 with Fibers=E2=80=99 own =E2=80=98sleep=
=E2=80=99 procedure, which does not block.

  Previously, the =E2=80=98daemonize=E2=80=99 action would remove those bin=
ding replacements,
  which could lead to blocking in shepherd, with symptoms such as =E2=80=98=
herd status=E2=80=99
  not responding.  This is now fixed.

  ** Gracefully handle failure to create a service=E2=80=99s log file
     (<https://issues.guix.gnu.org/76130>)

  If the file passed as #:log-file to =E2=80=98make-forkexec-constructor=E2=
=80=99 & co. could
  not be created, =E2=80=98herd status=E2=80=99 and similar commands would =
hang.  This is now
  fixed in two ways: by attempting to create the parent directory of the log
  file if it does not exist, and by reporting the failure and keeping the
  service =E2=80=98stopped=E2=80=99 in other cases.

  ** Timers honor daylight saving time (DST) changes
     (<https://issues.guix.gnu.org/75622>)

  Previously, timers would always sleep a fixed amount of time between two
  consecutive calendar events=E2=80=94e.g., 24h between two occurrences of =
a daily
  event=E2=80=94regardless of whether both events occur in the same timezon=
e or DST
  setting.  Timers now correctly honor DST changes=E2=80=94e.g., sleeping f=
or 25h
  between two daily events if the first one occurs on CEST (Central European
  Summer Time, or UTC+2) and the second one occurs on CET (Central European
  Time, or UTC+1).

  ** =E2=80=98cron-string->calendar-event=E2=80=99 can now interpret things=
 like =E2=80=9C*/2=E2=80=9D
     (<https://issues.guix.gnu.org/75843>)

  Until now, =E2=80=98cron-string->calendar-event=E2=80=99 would fail to in=
terpret
  specifications like "0 */2 * * *" (meaning: every two hours).  This is now
  fixed.

  ** =E2=80=98cron-string->calendar-event=E2=80=99 properly interprets star=
s for hours
     (<https://issues.guix.gnu.org/75836>)

  Previously, using a star for the hours in a cron specification such as
  "* * * * *" (meaning: every minute) would lead =E2=80=98cron-string->cale=
ndar-event=E2=80=99
  to erroneously report an error.  This is now fixed.

  ** =E2=80=98timer-service=E2=80=99 and =E2=80=98transient-service=E2=80=
=99 now honor #:requirement

  Previously they would both ignore it, returning a service that depends on
  nothing but the root service (which is probably acceptable most of the ti=
me).

  ** =E2=80=98default-message-destination-procedure=E2=80=99 is now exported

  That procedure of (shepherd service system-log) was documented but not
  exported.  This is now fixed.
