When I first installed gentoo, the docs told me to use
/etc/hostname...so I did.

I just recently updated, and now I am receiving warnings about using
/etc/hostname. It tells me to use /etc/conf.d/hostname.

So, I edited /etc/conf.d/hostname and added my name there.

On reboots, I am still getting this warning. I am worried about delete
/etc/hostname though...I fear that it still might be used by other
scripts...such as ddclient.

Is it okay to ignore this message for now?

What else do I need to do?
