I have nothing against longer keys but this sort of sentences ("DNSSEC
is simple, anyone can do it in five minutes") is a sure way to inflame
me. It is not sufficient to change the script, you also have to search
if it can break things later. A typical example would be the larger
response to the DNSKEY query. If changing the key size make it larger
than the MTU, it _may_ create problems.
