I grepped for "ssh" in /var/log/messages.

The failure on boot:
Feb 19 22:02:20 localhost vmunix: [    6.712592] random: ssh-keygen: uninitialized urandom read (32 bytes read)
Feb 19 22:02:10 localhost sshd[359]: Server listening on 0.0.0.0 port 22.
Feb 19 22:02:25 localhost shepherd[1]: Service ssh-daemon could not be started.

And then starting by hand:
Feb 19 22:03:48 localhost sshd[380]: Server listening on 0.0.0.0 port 22.
Feb 19 22:03:48 localhost sshd[380]: Server listening on :: port 22.
Feb 19 22:03:48 localhost shepherd[1]: Service ssh-daemon has been started.

It looks as if ssh-keygen takes too long; this is called from
openssh-activation in services/ssh.scm, with a comment
"Generate missing host keys". Are these regenerated at each boot?
If yes, is there a race condition, one action not waiting for the
previous one to finish?
