I'm using gentoo and I wanted to try out the latest NM so i downloaded
the cvs version and compiled it. I also emerge bind
net-dns/bind
Latest version available: 9.2.2-r3
Latest version installed: 9.2.2-r3]
Size of downloaded files: 4,975 kB
Homepage: http://www.isc.org/products/BIND/bind9.html
Description: BIND - Berkeley Internet Name Domain - Name Server
License: as-is
But when I start the network manager I get something like: Cannot start
nameserver...
What is causing this? I could figure out how to apply this: setsebool -P
named_disable_trans true
Help?

Hi,
I just committed to CVS support for running a local copy of BIND 9 which
acts as a caching nameserver. Actually, I guess I shouldn't say
"support", because it's actually now required.
There are a few reasons for this change, but the major ones are:
1) It's a step towards NetworkManager taking sole control over domain
resolution; the idea is other applications should never
touch /etc/resolv.conf directly. I plan to provide a D-BUS interface
for adding/removing nameservers.
2) It avoids issues with applications not picking up changes
to /etc/resolv.conf. Now resolv.conf just points to 127.0.0.1.
This setup seems to be working well for me, except for a bug in that on
a default Fedora Core 3 installation, bind won't be able to start
because the targeted SELinux policy can't differentiate the bind started
by NetworkManager from the "normal" bind. I'm going to try fixing this
soon in a generic way; it's come up for gnome-user-share running Apache
too. But as a temporary workaround, you can disable SELinux protection
for named with "setsebool -P named_disable_trans true". This should be
acceptable for now since it's pretty unlikely you're running a real
nameserver (i.e. an authoritative public-facing bind) on the same
machine as NetworkManager at the moment.
Anyways, testing and feedback is appreciated!
