=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.

  the Git repository.


=E2=80=A2 Changes since version 1.0.4

  ** =E2=80=98herd status system-log=E2=80=99 now displays the socket and k=
ernel log file

  When using the =E2=80=98system-log=E2=80=99 service, =E2=80=98herd status=
 system-log=E2=80=99 now shows the
  socket(s) it is listening to and the kernel log file it is reading (if an=
y).

  ** =E2=80=98system-log=E2=80=99 starts even if #:kernel-log-file is inacc=
essible
     (<https://issues.guix.gnu.org/77578>)

  It used to be that =E2=80=98system-log=E2=80=99 would fail to start if th=
e file specified as
  #:kernel-log-file was inaccessible.  This was unwise because that would t=
hen
  typically prevent most system services from starting; also, on Linux, the
  default #:kernel-log-file is /proc/kmsg, and that is inaccessible within
  containers.

  Failure to open #:kernel-log-file is now logged but is non-fatal.

  ** =E2=80=98system-log=E2=80=99 service reads /dev/klog on the Hurd
     (<https://issues.guix.gnu.org/77634>)

  The =E2=80=98system-log=E2=80=99 service would unconditionally read kerne=
l messages from
  /proc/kmsg, which is Linux-specific and nonexistent on the Hurd.  It now =
reads
  from /dev/klog on the Hurd.

  ** Fix bug that would cause a system-log test failure on the Hurd
     (<https://issues.guix.gnu.org/77634>)

  A bug would cause =E2=80=98system-log=E2=80=99 to keep polling the file p=
assed as
  #:kernel-log-file after it has reached end-of-file; this would significan=
tly
  slow down =E2=80=98shepherd=E2=80=99 on the Hurd, leading =E2=80=98tests/=
service/system-log.sh=E2=80=99 to
  fail.  This bug had no impact in real use where #:kernel-log-file points =
to an
  =E2=80=9Cendless=E2=80=9D file such as /proc/kmsg.

  ** Fix possible deadlock with timers hitting #:max-duration
     (<https://codeberg.org/shepherd/shepherd/issues/2>)

  A deadlock could occur when using a timer with #:max-duration that would
  result in shepherd being unable to handle process creation and terminatio=
n.
  The bug could happen only when #:max-duration is specified for the timer,=
 the
  timer=E2=80=99s process exceeds #:max-duration, and the timer=E2=80=99s p=
rocess does not
  terminate within 5 seconds after being sent SIGTERM by shepherd.

  ** Adjust =E2=80=98tests/pid-file.sh=E2=80=99 for systems where unlink(2)=
 returns EROFS on /
     (<https://issues.guix.gnu.org/77548>)

  This test used to assume that removing a nonexistent file on the root file
  system would return ENOENT, which is not the case on Linux when it is mou=
nted
  read-only.  Adjust to cope with that.
