I don't know why you would expect that.  What purpose would that serve?

The goal here is for programs to be able to look up "the IP address"
that belongs to $HOSTNAME.

If the hostname is "yosemite", then "yosemite" must appear in the
/etc/hosts file as an alias for whatever made-up FQDN is being used.

This is what Paul has.  What Paul has looks quite reasonable to me.
If 192.168.254.30 is in fact bound to an ethernet interface by a
static configuration (e.g. /etc/network/interfaces) then I would also
say it looks correct.

Not in the /etc/hosts file, they don't.  You may be thinking of BIND
configuration files.

I've never IN MY LIFE seen trailing dots on hostnames in /etc/hosts.
