```
$ cat /gnu/store/l1463gh71pm62404rxpwbzhwmz8dakl2-shepherd-mcron.scm
# […]
#:log-file (string-append %user-log-dir "/mcron.log")

$ env | grep XDG
# […]
XDG_STATE_HOME=/home/tanguy/.local/state

$ ls /home/tanguy/.local/state
log  nvim  shepherd  wireplumber

$ ls /home/tanguy/.local/state/log/
dbus.log  mcron.log  shepherd.log
```

I have no XDG "log" variable, but the `shepherd.log` in `~/.local/state/log/`
contains today's log, so… I guess it can write to the log folder.
The strange thing is that today mcron's log is in
`~/.local/state/shepherd/`?! 🤔
