That's good enough for now, thanks.  For some reason, Fedora puts it 
into /usr/lib/systemd, that's why I didn't spot it.

It's certainly better than nothing.  It's been done for recursive 
resolver caches, which are much, much larger.

Note that in this particularly, I'm not concerned about cache poisoning 
through spoofing, but due to algorithm bugs.  And for explaining those 
bugs, cache dumps help as well.
