Hi Patrice,

> Let me know if you find something else.

A few general notes:

* selinux can now be enforcing

* Why are these packages suggested to be installed:

oracle-instantclient-jdbc-10.2.0.4-1.*.rpm
oracle-instantclient-devel-10.2.0.4-1.*.rpm

* The notes about oracle_env.sh, ld.so.conf.d and tomcat 5 on x86_64
systems do not seem to be valid anymore.

* Why are you adding a 'Spacewalk for i386' channel? Do you plan do
deploy Spacewalk from itself?

* As you have defined:

'Cobbler requires tftp and xinetd services be turned on for PXE
provisioning functionality. Enable these services (y/n, default =
'y')?y'

during spacewalk-setup, it is not necessary to enable TFTP manually

* It is also not necessary to install osa-dispatcher manually, as it's
already there.

Best Regards
Marcus
