Hi Guix,
I got a question how to setup logging for daemons that are controlled by
shepherd that guix home creates. First some background info.
I have been slowly migrating my dotfiles from a GNU stow setup to guix
home. I'm currently using guix on a foreign distro that uses systemd.
Where systemd was controlling my user level daemons, e.g. ssh-agent.
But now that I use guix home, I have migrated them to shepherd. With
that I lost the handy logging you get from systemd. To mitigate that for
shepherd I'm right now using the #:log-file parameter, as suggested in
this thread [1], to send the output to a file.
[1] https://lists.gnu.org/archive/html/help-guix/2019-04/msg00178.html
Here's how I've setup the ssh-agent
--8<----------------------------------------------------------------------------
(define-public services
(list
(simple-service 'plt-ssh-environment
home-environment-variables-service-type
`(("SSH_AUTH_SOCK" . "${XDG_RUNTIME_DIR}/ssh-agent.socket")))
(simple-service 'plt-ssh-agent
home-shepherd-service-type
`(
,(shepherd-service
(provision '(ssh-agent))
(documentation "Run and control ssh key agent.")
(start #~(make-forkexec-constructor
`("ssh-agent" "-D" "-a"
,(format #f "~a/ssh-agent.socket" (getenv
"XDG_RUNTIME_DIR")))
#:log-file (format #f "~a/ssh-agent.log"
(getenv "XDG_LOG_HOME"))))
(stop #~(make-kill-destructor)))
))))
---------------------------------------------------------------------------->8--
I do want some better logging, than just dumping to a file, as otherwise
I'll eventual run out of disk space. I have been pretty spoiled with
systemd on that part, and I have very little experience with syslog.
Given that I'm on a foreign distro, I cannot use the syslog-service (as
far as I know). Does anyone have a good idea on how to set this it up?
For example if I setup syslog and put "/dev/log" in the #:log-file
parameter, will it work?
Or is syslog the wrong thing for user daemon logging? and instead I
should look for something else?
Thanks
