While these commands may work, it's worth pointing out that the service
name is actually ssh.service.  sshd.service is just an alias name for it.

In most situations, that won't matter, but if you attempt to make a
drop-in configuration directory to change the unit file, you WILL need
to use the correct service name.  I found this out the hard way, so I
thought I'd mention it to help others avoid the same pains.
