>Description:

after build_world and build_kernel
I can't start sshd
at attatched file you can see the problem
with /usr/bin/ssh-keygen it is not possible to write the private key, only the public key
/etc/rc.d/sshd start tries to generate dsa-key
and can not write a /etc/ssh/ssh_host_dsa_key
the file /etc/ssh/ssh_host_dsa_key.pub can be written in contrast 
(please see attatched file)
