Hello,
I am using BIND 9.16 as shipped with Ubuntu 20.04 LTS
named -v
BIND 9.16.1-Ubuntu (Stable Release) <id:d497c32>
I was under the impression that using map format with this version was
possible now. And I am actually able to create a map file and load a RPZ
zone as a master using a map format, this seems to work.
However, if I issue a simple rndc reload command, I see this log:
zone 'my.rpz': incompatible masterfile-format or database for a response
policy zone
reloading configuration failed: not implemented
and worse, if I update the textfile, change the serial, and rndc reload, I
get a segmentation fault;

my zone is declared as:
zone "my.rpz" {
type master;
masterfile-format map;
file "/var/lib/bind/my.rpz.map";
allow-query { localhost; };
allow-update { none; };
};
Is it possible to confirm that this is supposed to work in BIND 9.16?
Thanks in advance,
Ron
