prevents a server from skipping SSHFP lookup and forcing a new-hostkey dialog by offering only certificate keys
ssh-agent is now suspend-aware as it gets also CLOCK_BOOTTIME time

sshd-keygen.service depends on existence of /etc/ssh/ssh_host_ecdsa_key instead of /etc/ssh/ssh_host_dsa_key by default
ssh-copy-id is run in so called legacy mode when SSH_COPY_ID_LEGACY variable is set
