  I'm not trying to be clever, I just don't like to type it twice if I
can avoid it and the typing the higher the chance for a typo.  I don't
have a problem having both forms.  I'll add it and see what you think.

  Normally, I expect, if people don't understand a command, they will
refer to the man page for the command.  However, to my constant
disappointment, I understand that many people aren't looking for long
term knowledge improvement, they are looking for a recipe to blindly

  Having both forms should make it plain that people can use any
convention they wish.  System administration is not a fixed target.
Like many things, there are many ways to accomplish the same result.
When approaching a system that someone else is administrating, we should
try to maintain the existing conventions instead of forcing our own
ideas onto a server for which we are not the primary responsible party.

  Sections 6 and 7 are optional.  There are certainly arguments against
customization.  In the past, upgrades might have replaced all files
including configuration files.  In that case, creating a vhosts.conf
file in the conf.d directory to separate the directive would have been a
must.  However, the Linux distributions I have used for the past decade
or so have avoided replacing existing configuration files, expecting
they might be customized.

  That said, I like the suggestion.  It would allow for the virtual host
files to be packaged into an RPM file that could be installed on
multiple web hosts.
