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 -- s/Fred[re]+i[ck]+/Fredrik/g
