sudo yum -y install openoffice.org-writer sudo yum -y install openoffice.org-calc sudo yum -y install openoffice.org-draw openoffice.org-impress
You can install just the components you need. To find out what is available, once you have Xfce or some other desktop environment running, start a terminal and type the following at the shell prompt:
yum list|grep openoffice
This will produce about eighty lines of output that should start something like this:
openoffice.org-calc.i386 1:2.3.0-6.4.fc7 olpc_koji-ship2 openoffice.org-core.i386 1:2.3.0-6.4.fc7 olpc_koji-ship2 openoffice.org-draw.i386 1:2.3.0-6.4.fc7 olpc_koji-ship2 openoffice.org-impress.i386 1:2.3.0-6.4.fc7 olpc_koji-ship2 openoffice.org-writer.i386 1:2.3.0-6.4.fc7 olpc_koji-ship2 ...
Then just use yum to install whichever packages you want (use package names without the “.i386″ part). For example (as root):
yum install openoffice.org-writer yum install openoffice.org-calc yum install openoffice.org-draw openoffice.org-impress
By the way, most of the space is taken up by the infrastructure; adding more components takes up little extra space.
