Re: sshd issues on Windows 10 version 1803

[Hiya Z <hiya dot zyx at gmail dot com>]

Upon upgrading another 1709 node (with working Cygwin sshd), the 1803
update clobbered the sshd service registry tree. The older Cygwin sshd key
was deleted and a new sshd service got created pointing to
%SystemRoot%\System32\OpenSSH\sshd.exe.
This is different from what I observed on the 1st node that I upgraded a
few weeks ago (wherein the Cygwin sshd registry tree was left intact). I
deleted the sshd service, rerun ssh-host-config, and am back to random
failed auto-restarts of sshd.

I think there is a myriad of issues here, the least of which is MS
hijacking the "sshd" service name. As a minimum, the default 'service_name'
in ssh-host-config should be changed to not conflict with "sshd". Maybe
ssh-host-config should also consider deleting any pre-existing "sshd"
service and then recreate a new one. The FAQ may require some mention as
well.

I got another hit of this conflict on the web at
https://gist.github.com/roxlu/5038729  (last few comments).

Thanks.
