Out of the box, an LFS system will report (None) as the domainname.
You can see this if you try to put the domainname into /etc/issue. For
a long time I'd kept a local patch on init.d/localnet that looks for
DOMAINNAME in /etc/sysconfig/network and then used the `domainname'
utility from net-tools to set it. Obviously, this wouldn't work for
LFS since there's no net-tools.
Recently I discovered that you can do the same thing with sysctl
through the parameter kernel.domainname. Attached patch works on my
system. There could be some corresponding text in Ch. 7 about setting
the domainname.
What do you guys think?
