mcron

[Benjamin Slade <beoram@gmail.com>]

nnI'm having trouble getting mcron to work. I have configured it in
/etc/config.scm similarly to the example given in the manual, but it the
mcron service seems to immediately stop. I've tried `sudo herd enable
mcron` and `sudo herd start mcron`, which work, but then when I check
its status, I find mcron is disabled and not running.

My /etc/config.scm looks like this:

`````
;; This is an operating system configuration template
;; for a "desktop" setup with GNOME and Xfce where the
;; root partition is encrypted with LUKS.

	(gnu packages guile) (gnu packages backup))

(use-package-modules certs gnome wm base idutils xorg)

I'm not sure why I can't get mcron to start.
