This is correct. Always put the fully qualified host name first, then
the aliases. When you type 'hostname', you should get the fully
qualified host name, not the short name. The line should read:
127.0.0.1 bison.example.com bison localhost localhost.localdomain
or break it up into the more proper:
127.0.0.1 localhost localhost.localdomain
1.2.3.4 bison.example.com bison
with the host's IP address pointing to the fully qualified name,
assuming that the domain is example.com of course.

You're not wrong.
