Comment 139 for bug 959037

If "libnss-nm-dns" would make it easier to introduce per-user caching and/or if it improved security then those would be important benefits.

Currently nm-dnsmasq has caching disabled because of concerns about cache poisoning and information leakage.

If there have already been discussions of per-user caching in Ubuntu then someone please give me the link.

The only approach that I have seen so far is per-user nscd in Solaris and (I now see) FreeBSD.
