Ovirt devel - Jun 2008 - [PATCH]: Shrink the managed node image to under 64MB

All,
     Attached is a patch that cleans up the managed node image some more, so
that the ISO size is 57MB, the overall /tftpboot directory (for PXE) is 62MB,
and the runtime image (right after boot) is ~152MB.
     It's a larger patch than it looks, mostly because I re-organized the
way we
were getting rid of stray kernel modules.
     Note that keeping the image this small depends on 3 things:

a)  Re-writing the /sbin/ovirt-identify-node script in bash or C, which I
believe Darryl has already started on.  This is because I explicitly remove
python.

b)  Having a libvirt version that *doesn't* require python.  This is a
little
tricky; the version of libvirt currently in updates (0.4.2-3) does require
python since it requires lokkit.  However, the version in updates-testing
(0.4.2-4) doesn't require python, since lokkit was dropped.  That being
said, I
believe the plan is for libvirt to re-enable lokkit in the future, so we will
have to watch out for that.

c)  Having a collectd RPM that doesn't require rrdtool.  Alan and I split
the
collectd RPM up yesterday, so you can install collectd without rrdtool, but that
change has not yet been pushed to the repositories.

Both b) and c) can be currently solved by pointing at
http://ovirt.org/repos/ovirt/9/x86_64 in your repos.ks, since we are hosting the
updated packages for both libvirt and collectd there.  We will need to fix
ovirt-identify-node asap to solve a).

Ok, this pain with lokkit has gone too far. It must die a horrible and
flaming death. All we're using it for is to persist the iptables config
we need, which basically comes down to writing a simple text file. We
really don't need python todo that.

ACK - this makes shell version of /sbin/ovirt-identify-node a priority

ACK on visual review though I don't have time to test it myself presently...

Committed (actually, committed yesterday, but forgot to send out a notice).
