Comment:
This is caused by `xbps-src` removing empty directories during post-install.
```
=> usbguard-1.0.0_3: running post-install hook: 03-remove-empty-dirs ...
=> WARNING: usbguard-1.0.0_3: removed empty dir: /var/log/usbguard
=> WARNING: usbguard-1.0.0_3: removed empty dir: /var/log
=> WARNING: usbguard-1.0.0_3: removed empty dir: /var
=> WARNING: usbguard-1.0.0_3: removed empty dir: /etc/usbguard/IPCAccessControl.d
```
I fixed this by adding the directory to `make_dirs`. The template already does this for `/var/log/usbguard`. I can make a pull request, but I would like to get a comment from a dev first.
