changing domain name -- what will break?

[Jim Prewett]

All,
I'm just about to change my domain name.  I'm wondering what problems to
expect related to openssh.  I want to change as little as possible (no new
keys, etc.)

So far, I've seen that I'll need to modify my system-wide
ssh_known_hosts[2] files and my users known_hosts[2] files (I'm planning
on providing them a simple shell script that basically runs something like
sed 's/olddomain.edu/newdomain.edu/g' and encouraging them to run it).

In the ssh_configs, I may have to change any of the Host
declarations.  Again a little sed (like above) seems like it would
work. 

In my experience, the user's keys are independant of the host on which
they were generated.

What (if anything) am I missing?  Am I just being overly paranoid?

I can find no mention of this in the FAQ nor the list archives.

Thanks,
Jim
