The title basically says it all. But mind: host key, not the login key.And if they're not compatible out of the box, is there a way to convert between them - and what would be the steps in that case?Rationale: it would be nice to be able to bring up a dropbear instance in the scope of the initrd, if boot fails, but do so by incorporating the host keys (via initramfs-tools hooks) from OpenSSH that is normally installed on the host.
Are dropbear and OpenSSH host keys compatible?
