space. For the host files there are three options:
1) OpenSSH is used on the host machine, OpenSSH's host
   keys are converted to Dropbear format and copied to the
2) Dropbear is used on the host machine, Dropbear's host

3) Neither OpenSSH or Dropbear is used on the host
   machine and no host keys exist, Dropbear host keys are
   generated and copied to the ramdisk.

Concerning key files, root's authorized_keys are copied to
ramdisk if they exist. Riku Voipio has verified that both
OpenSSH and Dropbear use the same key format for RSA
