I don't really like the first couple of sentences here. How about:

The <command>ssh</command> server in the installer uses a default configuration that does not send keep-alive packets. In principle, a connection to the system being installed should be kept open indefinitely.

Keep-alive packets aren't really a timeout, so the previous version jarred with me a bit.

I'd add a bit in the last sentence:

... connection to be dropped (for example if keep-alive packets are sent during a brief network outage, from which <command>ssh</command> would otherwise have recovered), so ...

Otherwise sounds good to me.
