I made the change and everything seems to be working fine. Thanks for all
your advice and enjoy the holidays!

Yes, I think you're right. THe time period is short enough, though,
that I think I can live with that.
If you script it (kadmin *is* scriptable in recent MIT, with some pain), the
time between creating and adding to the first KeyFile can be milliseconds;
script pushing that to the other servers and it's still likely to be a few
seconds at most. If using Heimdal, you can use 'ktutil get' and do the first
one in effectively a single operation (ktutil get -k AFS3KEYFILE:...
afs/cell@REALM). Then Kerberos-authenticated parallel ssh to push to the
other servers for minimum latency. :)
