Install OS

Use fedora 12 i386 net install to install a base os. I did the install with 256mb of memory installed and it gave me a very basic system install. I am not sure if this is the same installed state you would have if there was > 256mb of ram.

Create cltbld user

As root:

useradd cltbld
passwd cltbld

Install Packages

We need some packages to get things running. The firefox install is to make sure all the runtime libraries are present.

yum install -y openssh-clients Xvfb firefox wget mercurial python-devel metacity dejavu-s*
