Actually, logging has to be enabled for bind, not for dhcp -- took me a while to figure that out
I've enabled it, but it throws no hints at all...
As an aside, I've tried manually doing an nsupdate, and it sorta works, but I can only resolve the host to the IP, not the other way around. Maybe it's because I don't know how to use nsupdate, but this is what I tried:
# nsupdate -y my-key:somekey
update add hostname 86400 A 192.168.0.123
And after that I can do an nslookup for the hostname, but not for the IP address...
If anyone else has a hint on what the issue could be, by all means, help a clueless soul out
