USB booting :: after CF IDE boot: SSH hostkey problem

Hi,

after booting from a CF card via IDE I want to start sshd and login in via ssh.
I used the frugal_instal script, just changed the possible device name from hda to hdc, it just worked fine. I added the ssh daemon via this script and managed to add my user account in the backup/restore mechanism.
I wanted to add the sshd configuration files to the restore mechanism, but I see that the ssh daemon is started before the files are restored. So every time there is a new hostkey, this brings up serious warnings on the ssh client side...
A second partition is a available (used by backup/restore).

Can I direct sshd to use a configuration on the fixed partition?
Or should I start the sshd via a script after booting and restoring the host key files?
Can I switch of the automatic backup during shutdown?

Thanks,
Jens
