Kickstart Default template contains this...

# install epel if we can
<%= @epel -%>

Which results in this command during the kickstart install...

# install epel if we can
su -c 'rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm'

Which fails if the host is behind a proxy.

This is created by code in app/models/redhat.rb.

It would be nice if it could detect whether the host had a proxy configured, and if so modify the rpm command like so...

# install epel if we can
su -c 'rpm --httphost PROXY_URL --httpport PROXYPORT -Uvh http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm'
