Isn't sufficient to configure the root trust anchor inside "managed-keys {};"
statement? If I understand correctly the key should be automatically
updated, shouldn't it?

For 9.7 yes.


I just updated to 9.7.2-P3 and got this message on start:
Dec  1 10:52:01 maplepark named[20356]: starting BIND 9.7.2-P3 -u named
Dec  1 10:52:01 maplepark named[20356]: built with defaults

Dec 1 10:52:01 maplepark named[20356]: loading configuration from '/etc/named.conf' Dec 1 10:52:01 maplepark named[20356]: reading built-in trusted keys from file '/etc/bind.keys'

I had removed that file for -P2 but the sudo make install of -P3 re-wrote it:
[...@maplepark:~/src/bind-9.7.2-P3]$grep bind.keys typescript /usr/bin/install -c -m 644 ./bind.keys /etc
so it is back.


I do have a managed-keys statement in my named.conf:
managed-keys {
"." initial-key 257 3 8 "AwEAAagAIKlVZrpC6Ia7gEzahOR+9W29euxhJhVVLOyQbSEW0O8gcCjFFVQUTf6v58fLjwBd0YI0EzrAcQqBGCzh/RStIoO8g0NfnfL2MTJRkxoXbfDaUeVPQuYEhg37NZWAJQ9VnMVDxP/VHL496M/QZxkjf5/Efucp2gaDX6RS6CXpoY68LsvPVjR0ZSwzz1apAzvN9dlzEheX7ICJBBtuA6G3LQpzW5hOA2hzCTMjJPJ8LbqF6dsV6DoBQzgul0sGIcGOYl7OyQdXfZ57relSQageu+ipAdTTJ25AsRTAoub8ONGcLmqrAmRLKBP1dfwhYB4N7knNnulqQxA+Uk1ihz0=";
};

and it seems to run OK so far.

My question is whether the built-in trusted keys (/etc/bind.keys) is necessary or not in 9.7.2-P3. I am assuming it is as the make step set it up.

It is a DLV needed as a trust ancor until DNSSEC is chained from the DNS root downwards. See http://www.isc.org/solutions/dlv for details.
