I have been using Ubuntu since 2006 and NM since whenever it became the
default and have never seen that behaviour EXCEPT that it has
overwritten resolv.conf. That's why I disable dnsmasq, so I have more
direct control over name service.

I've found it very usable for most of its existence, and I'm a network
guy so I'm pretty demanding. I've found that NM gets on with giving me
mobility, easy of use, ease of setting up VPNs and so on, while
/etc/network/interfaces gives me the direct control I often need.
They've worked beside each other for a long time and very effectively.
I'm having a hard time imagining what you might have wanted to do that
NM got in the way of.

Sometimes when I'm working with "ip" and adding addresses or
subinterfaces, mucking about with routes or metrics or whatever, I will
forget to put the relevant interface into /etc/network/interfaces and
restart NM. So five minutes later NM undoes everything I did :-)

Internode was the first provider in Australia to deliver IPv6 on its
standard offerings.

However, if you want IPv6, it is really very simple to set up a tunnel
with (e.g.) Hurricane Electric, and it's free. You can do it from any
Linux box, or, if you want it always-on or delivered to your whole home
network you can set up a tunnel on any good-quality router. I use
MikroTik. Once your router is providing IPv6 connectivity, whether via
a tunnel or natively, your home devices will generally just start using
it automatically. NAT disappears for IPv6, so check the packet filters
on the router and any devices that traffic is allowed through to.
