Current state:

1. 1. 1. Option: SSHKeyLocation
2. Location of public keys for SSH checks
   #
3. Mandatory: no
4. Default:
5. SSHKeyLocation=

Why only public keys mentioned?
We need public and private keys for SSH checks!

I suggest to change it to: "Location of public and private keys for SSH checks"

should be updated as well.
