It turns out that dhcpd(8) didn't work with "hmac-sha256" keys in
NetBSD 6.1_STABLE as well:
Aug 21 14:08:23 colwyn dhcpd: Unable to add forward map from
MacBook.zhadum.intern to 192.168.25.186: bad DNS key
As far as I can tell it only supports "HMAC-MD5.SIG-ALG.REG.INT" keys
which is of course not very satisfactory. However Google suggests that
this problem also affects various Linux distributions (e.g. Arch Linux
or Ubuntu). So it seems to be a problem with ISCP DHCP Daemon itself.
However the "nsupdate" behaviour is still a regression. It definitely
worked with the "hmac-256" key under NetBSD 6.1_STABLE.
