hostname setting in rc.conf ignored?

[Mike Barborak]

Hello,

I have a FreeBSD 4.7-RELEASE-p28 server that was initially configured with
the hostname mydomain.com. I am trying to permanently change that to be
www.mydomain.com. I have added this line to my /etc/rc.conf file:

hostname="www.mydomain.com"

but after restarting the server it continues to return mydomain.com when i
run the command hostname. Can anyone tell me what I am doing wrong?

Thanks,
Mike
