Hi,
Does anyone have a working job specification for Mcron that uses
"with-mail-out"? [1] I have some trouble providing (mcron redirect)
inside the gexp. Thanks!
Kind regards
Felix

Sorry, I don't, but I'd be interested in a concrete example as well.

I figured out a procedure for my home environment:
--8<---------------cut here---------------start------------->8---
(use-modules (gnu packages guile-xyz)) ;to load mcron redirect
#~(job
'(next-minute)
#$(program-file
"ls.scm"
#~(begin
(use-modules (mcron redirect))
(setenv "PATH" (string-append (getenv "PATH")
":/run/setuid-programs/"))
(with-mail-out (lambda ()
(system (string-append #$coreutils
"/bin/ls")))
"user@localhost"))))
--8<---------------cut here---------------end--------------->8---
It looks a slightly different when applying this job to a system wide
declaration:
--8<---------------cut here---------------start------------->8---
(use-modules (gnu packages guile-xyz)) ;to load mcron redirect
#~(job
'(next-minute)
#$(program-file
"ls.scm"
(with-extensions
(list mcron)
#~(begin
(use-modules (mcron redirect))
(setenv "PATH"
(string-append (getenv "PATH")
":/run/setuid-programs/"))
(with-mail-out (lambda ()
(system (string-append #$coreutils
"/bin/ls"))))))))
--8<---------------cut here---------------end--------------->8---
The action has to have its PATH extended, otherwise it fails to find
sendmail. With this I have mcron sending mail to me.
The documentation of mcron does not state that the user name is optional.
Have a nice day,

Thanks for that!
Do you provide a 'sendmail' executable in your system profile? If so,
should the system PATH include "/run/setuid-programs"?
Kind regards

I haven OpenSMTPd running as a service and have provided the packet
through the system profile. But /run/setuid-programs is not available
for mcron. Should it be? And if, how can I change that?
Kind regards,

I understand your question now. Please disregard my previous message.
Sendmail is available through /run/current-system/profile/sbin and
/run/setuid-programs/sendmail. Both are provided by OpenSMTPd. I don't
have sendmail in my user profile, and am trying to get on with mailutils
and OpenSMTPd only for the time being. I have no need for msmtpd yet.
Mcron's service PATH contains only /run/current-system/profile/bin and
thus can't find sendmail.
If I use my previous job example and leave (setenv ...) out, I get the
following error:
--8<---------------cut here---------------start------------->8---
2024-08-08 12:17:00 19819 /gnu/store/ir80y6y5g4w1qf2fcqm71lv8rh2gppwq-setuid-sans.scm: running...

--8<---------------cut here---------------end--------------->8---
This is slowly giving me a slight headache. Should mcron not know
about sbin, and maybe more so about setuid binaries?
The PATH in gnu/services/mcron.scm is defined a follows:
--8<---------------cut here---------------start------------->8---
#:environment-variables
(cons* "GUILE_AUTO_COMPILE=0"
"PATH=/run/current-system/profile/bin"
(remove (cut string-prefix? "PATH=" <>)
(environ)))
--8<---------------cut here---------------end--------------->8---
This applies generally. Is that not too limiting?
Kind regards
