I'm beginning to think my system configuration is a mess.  It started with
worrying about Postfix, but has quickly escalated.

I was trying to figure out what Postfix knows and where it knows it when
I found that I seem to have no domain name.  That is, the shell command
domainname(1) returns "(none)".  This seems odd, because I've got
it set up as nearly as I can see according to gentoo docs
  http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=8#doc_chap2
since my /etc/conf.d/net contains (among other things)
  dns_domain="kosmanor.com"
BTW: it also says to set dns_domain_lo, but I have no name for my
internal network, and
haven't seen a reason to create one.

Nevertheless, even the system calls getdomainname(2) and uname(2) return the
string "(none)".

What am I missing?
