George, et. al.,

When I think about how to improve the XS installation process it seems to me 
that separating the linux install from the XS packages is a good idea. 
Ideally you would install the latest distro (probably of fedora) using the 
minimal kickstart file plus packages needed by the xs, such as httpd, in 
order to get the best hardware support, and then afterwards use yum or some 
automated process to install the actual xs packages.  I like the way XS-AU 
has created a package group for the xs; the standard kickstart file mixes 
things together.   I also like installing from something that you can 
actually copy files to without having to burn a new copy, like a USB or the 
network install I experimented with.

But I wonder how XS servers are actually set up in ongoing deployments, for 
example:

How is the Server typically installed and configured:

Naive User at an isolated site?
Expert User at an isolated site?
Expert User at central location?  (This would be my guess.)
Are there any target Server machines with optical drives that have only a 
CDROM (vs. DVDROM)?  (I have machines older than 10 years that have dvd and 
the couple cdroms don't work any more.)
Are there any target Server machines that cannot boot from USB? (None of my 
old machines can.)

What XO Services are used:

Presence/Activation Server?
Chat Server?
Activity Server?
Moodle Content?
Moodle User Management?
Backup?
DHCP/Name Server/Routing?
Web Access Filtering?
Other?
What do XOs do when there is no server?

What are the impediments to installing XS packages on any arbitrary fedora 
version:

version of python?  (if we need to rewrite, should we go to 3.x, rather than 
2.7?)
version of php?
version of moodle? (is there a reason not to be on 2.x?)

Finally, have all the deployments rolled the versions that they need and is 
there any impetus to do further upgrades?
