[ydl-gen] setting the hostname in YDL 4.1

[Nathan Moore]

Hi Chris,

Thanks for responding so quickly.

Yes, I've heard from my sysadmin that when my machine sends out an  
initial DHCP address request, the (DNS server?) network identifies my  
machine's mac address and associates it with my machine's  
"hostname".  What I don't understand is how to tell our DNS server  
what I'd like the machine to be called.  I get the impression from  
our sysadmin the this naming is automatic and depends on information  
that I somehow send to the DNS server.

In the same vein, if I have no control over my machine's hostname,  
why does one step of the YDL install process involve "setting the  
hostname"?  Is this step a placebo to make me feel like I have more  
control?

Thanks so much for your reply!
