No.  The "must be owned by root" in sshd is the original upstream error
message.  The test leading to the message on the other hand is tweaked
for Cygwin to test if the /var/empty file is owned by the user running
sshd.  So, if you run sshd from the command line, it refuses to run if
/var/empty isn't owned by your current user account.  If you're running
sshd as service from the XXXXXXXXXX+cyg_server account, /var/empty must
be owned by the XXXXXXXXXX+cyg_server account.

Does that help?
