It's confusing... Dracut for example expects it in 
/etc/sysconfig/ima-policy:

https://github.com/dracutdevs/dracut/blob/master/modules.d/98integrity/ima-policy-load.sh#L10

So following that either one has to change. I chose to change systemd. 
To me /etc/default on Debian systems is the equivalent of /etc/sysconfig 
on RPM based ones (or at least RedHat based ones), so that's where this 
is coming from.

Fine, if that's the common understanding that the proposed directories 
are not appropriate.
