Re: How to configure smartd and send notifications?

[Tristan Kohl via <help-guix@gnu.org>]

Hello Felix,

my last message was not to critizise your help but rather my frustration with my own limited progress. I really appreciate the help!

program-file at least results in a usable thing however since the script gets executed by smard I get the "command not found" in my logs. It seems like curl is not in PATH for smartd. Do I need to import something into the gexp?

Also those env variables are defined by smartd during runtime depending on which drive produced the error. Therefore I need shell expansion/env variables and have to use system (without *) imho.

This is the current state:

(define-smartd-send-ntfy
  (program-file "send-ntfy"
    #~(system
      (string-append "curl " "-H \"Title: $SMARTD_SUBJECT\" " ...))))

Note: when using system* the error is:
In execvp of curl: No such file or directory

Thanks for bearing with me!
Tristan
