Using a tool called Revisor, you can easily spin your own Orange Sombrero.
Here's the instructions to get you started. See also: Running Revisor From Source. It assumes you have configured sudo for your normal user account.
# Clone the source repository
git clone git://git.fedorahosted.org/revisor
# Navigate into the newly created directory
cd revisor
# Install required packages
yum install comps-extras createrepo rhpl pykickstart livecd-tools \
anaconda-runtime squashfs-tools busybox-anaconda notify-python usermode \
pam python automake intltool gettext desktop-file-utils glib2-devel gcc \
cobbler koan deltarpm pygtk pygtk2-libglade gnome-python2-gconf \
system-config-kickstart jigdo livecd-tools python-virtinst
# Checkout the appropriate branch
git checkout --track -b rebrand-devel origin/rebrand-devel
# Automake foo
autoreconf -v && ./configure
# Make it run from source
./switchhere
Then, type the following command to create your own version of Orange Sombrero:
sudo ./revisor.py --cli --config /etc/revisor-unity/orangesombrero.conf --model os9-i386-single-cd
