How can I have the same ssh key for dual boot (ssh-keygen)

[Martin Hecht]

one thing not yet mentioned by others:
You should not only synchronize the keys in ~/.ssh/ but, more important,
in order to avoid that all other clients complain about a suspeced man
in the middle attack, you should copy the host keys located in /etc/ssh/
(e.g. by temporarily putting them on an usb medium during reboot, or by
mounting the root partition of the other linux e.g. somewhere below /mnt
- just once for copying the files). Then, clean up the
~/.ssh/known_hosts files on the other machines.
