The single problem with func and the rest of the ET stuff is that they are not the easiest to
figure out how the hell to make them useful.
Multi-system administration with Func

Cobbler, for a quick glance, sounds like a souped-up version of the Solaris 10 Jumpstart
feature, which can make rolling out new installations somewhat easier.
This comment doesn't really add much, but I'm hoping there is someone with more Cobbler
experience who knows Jumpstart that can pontificate.

I have no experience of jumpstart, but I believe it's something more like redhat kickstart,
no? I.e. a system for automated installs with a file containing answers to all the questions
that are usually asked when going through the interactive installer.
cobbler is more like a system for managing kickstarts and pxe boot infrastructure. It has 3
basic types of objects; distros (pxe boot images), profiles (associates a distro with a
specific kickstart file) and finally systems (associates a profile with a MAC and IP address).
So you create a bunch of systems with cobbler, and cobbler can generate a dhcp config (based
on a template you can modify e.g. to include non-cobblerized entries), sets up a tftp server
etc. Then you just PXE boot the systems and they are automatically installed with the profiles
you have specified.

You actually have a specific complaint, or are you just
spreading FUD? These tools are currently used by
large partner companies of Red Hat, who obviously find
them useful otherwise they wouldn't continue to use them.

No, this is not FUD. I really love all the ET stuff Red Hat is working on, but when I put on
my "busy sysadmin" hat, I realized I got really lost trying to figure out a) where to start b)
was the pain of setup worth the reward.

I'd really like to find out what issues you were
having. (Email me, r j o n e s (at) r e d h a t dot c o m)
I'm working on a set of command line tools for
administrators of small-scale virtual machine
deployments, so you can type commands such as
virt-df to get a 'df'-style listing
of the disks of all your virtual machines, or
virt-ps to get process listings
from all of them.
You could also start with the list of links at the
bottom of this page: http://virt-manager.org/.
However it's not intended that you should need to
compile everything from source, unless you want to
join in with development. Everything either
is or will be in Fedora, and the good bits should
eventually make it into RHEL.

Actually one easy example is doing an update of some package on all your systems, but only
where that service is a version with a known security risk.
I can easily think of many tasks which I had to do fairly recently where a package like func
would have helped me. I can imagine though that if you don't have at least a few systems to
manage that setting up something like func is more a bother than a helper.
