These are the TYPE 65534 records?  E.g. dig axfr reports these:
   example.com. 0     IN      TYPE65534 \# 5 0797800001

How can I tell that key changes are 'stable'?  (The only changes going on at
are the automagic re-signing. (sig-validity-interval 8 2; + dhcp updates)

Will nsupdate allow me to delete these?  (all the zones are, of course,
The ARM (p 24) seems to indicate that bind 9.7 still uses them - are you
saying that I 
need to delete them under the old version before starting the new?  

This would a bit tricky, since as long as the master is up, dhcp and other
DDNS updates 
will arrive at unpredictable times - and of course that triggers resigning.
If the master
is down - I guess I could axfr from one of the slaves to get a consistent
copy.  But
if I restart the master with those files (dozens of them), I'd have to
delete the
journals - would state then be lost?  Or do the slaves have everything

>> No.
So would you suggest upgrading the slaves before the master, or the master
And I can use my existing key-directory (ies - 1/view)  and zone/journal
files - no 
changes required?

I'm looking forward to these - once I understand how they work and how to
them to do the most magic for me... And how to get the rest into my web gui
& cron -
E.g. I want to end up with a button that says "roll key for this zone", with
the delays and key generation and adds and removes just happening...
