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---

--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
