Daniel,
Installing everything on a remote server is NOT a good idea.  You are
opening up your server to vulnerabilities and causing things to run in
memory that you have no use for.

You are also putting every tool that a bad guy would need already on
your server, so he can do just about anything he wants if he gets
access.

It is, of course, your server ... so if you want to install everything,
that is up to you.

There is no "install everything" option in yum groupinstall.  The yum
group features use the same comps.xml file as the anaconda installer, so
we won't change it. (yum uses it differently ... and there is no
"install everything")

If you haven't done any upgrades or added any software outside the
distro, you might be able to use:

system-config-packages

(if you have run yum or up2date to update the system, system-config-
packages will no longer work)
