Not directly helping you with cron, but any reason why you are using cron
instead of systemd timers? The functionality is the same, but output is
logged to journald, status is kept and accessible using systemctl.
Just add a startAt definition to your systemd service.

I see here that there are upstream issues with cron as far as setting user
crontab entries:

But I'm having trouble setting the system ones as well. I think if they
didn't work
at all a lot of other things would fail, so I must be setting something
wrong. This
simple test doesn't put any files in /tmp or send any emails:
services.cron = {
enable = true;
mailto = jef...@gmail.com;
systemCronJobs = [
* * * * * test ls -l / /tmp/cronout 21
* * * * *
/nix/store/wc472nw0kyw0iwgl6352ii5czxd97js2-coreutils-8.23/bin/test
/nix/store/wc472nw0kyw0iwgl6352ii5czxd97js2-coreutils-8.23/bin/ls -l /
/tmp/cronout 21
];
};
I've checked that it does get written to /etc/crontab:
SHELL=/nix/store/xlxjcjq3bnbwnzq82irlzwxhmx6fvc2w-bash-4.3-p33/bin/bash
PATH=/nix/store/fpqvi360cimx3h1kxdxfvkyip52d1i8y-system-path/bin:/nix/store/fpqvi360cimx3h1kxdxfvkyip52d1i8y-system-path/sbin
MAILTO=jef...@gmail.com
NIX_CONF_DIR=/etc/nix
* * * * * test ls -l / /tmp/cronout 21
* * * * *
/nix/store/wc472nw0kyw0iwgl6352ii5czxd97js2-coreutils-8.23/bin/test
/nix/store/wc472nw0kyw0iwgl6352ii5czxd97js2-coreutils-8.23/bin/ls -l /
/tmp/cronout 21
And that the test and ls binaries are on that PATH. Anything else I should
try?
