This reverts commit 1a74eedd07. It
breaks NixOps, which expects that
rm -f /etc/ssh/ssh_host_ed25519_key*
systemctl restart sshd
cat /etc/ssh/ssh_host_ed25519_key.pub
works.
*** NixOS *** NixOS is a Linux distribution based on the purely functional package management system Nix. More information can be found at http://nixos.org/nixos and in the manual in doc/manual.
