This is now part of the ‘devel’ branch. This is pretty much the last
feature I wanted to have for 1.0.
If you want to use this new ‘system-log’ service instead of syslogd,
here’s how you can change your system configuration:
--8<---------------cut here---------------start------------->8---
(define system-log-service-type
(shepherd-service-type
'shepherd-system-log
(const (shepherd-service
(documentation "Shepherd's built-in system log (syslogd).")
(provision '(system-log syslogd))
(modules '((shepherd service system-log)))
(free-form #~(system-log-service))))
#t
(description
"Shepherd's built-in system log (syslogd).")))
(operating-system
;; …
(services (cons* (service system-log-service-type)
;; …
(modify-services %desktop-services
;; …
(delete syslog-service-type))))) ;replaced by the
Shepherd's
--8<---------------cut here---------------end--------------->8---
You need to be using the Shepherd from the ‘devel’ branch of course; see
the instructions in the Shepherd’s ‘README’ for this.
Once running, it gives something like this:
--8<---------------cut here---------------start------------->8---
$ sudo /run/current-system/profile/bin/herd status syslogd
Status of system-log:

And it’s now integrated with the new ‘log-rotation’ service:
