This doesn't seem like a naming issue.  A hostrealm module which reads
from the configuration profile is inherently easy to confuse with a
profile module, if you aren't keeping track of what you're looking at.

Not that I can see.  hostrealm modules do not depend on one another.
The built-in modules do need to have a well-defined order so that we can
match the current behavior, but that is not a dependency relationship,
just a precedence order.

I'm not sure what you mean.  Plugin modules now have a precisely defined
order, with or without explicit configuration.

http://web.mit.edu/kerberos/krb5-devel/doc/admin/conf_files/krb5_conf.html#plugins
documents plugin order in the second-to-last paragraph.

I also plan to expand host_config.rst to discuss plugin configuration in
greater detail, but not right away.
