Yes, imaging is a possibility and that's what we've used in the past,
but it is far from VMWare's "click snapshot" (less than a few seconds)
and snapping back to it. It's also a big problem with storage... with
a VM it's relatively manageable (1.6 gig for XP)... and I do not need
multiple partitions. I can also create a "standard build" with one VM
image that works on everything (in fact, I do this.. I build a
standard something, and give it to our CEO to use, and he literally
clicks the "play" button in Parallels. You cannot do that with OS
X... unless of course he is on identical hardware. Now that their are
MacPros, iMacs, G4's, G5's, macminis, etc imaging with OS X is not as
simple as one build fits all. Especially with the MacPro... I won;t
even go into what happened with our MacPro when we experimented with
different images.

Not to pooh-pooh the idea of virtualization for testing, because it's
frankly a great mechanism, you absolutely do not have to rebuild from
scratch if you want to roll back. There are so many ways to not do
this - cloning, imaging, asr to another volume/partition, etc. You
maintain a master image, and you do not update that one. You clone
that image, and then perform updates/testing/remediation, and once
everything is determined to be acceptable, that becomes your new
master. Any rollbacks can be performed instantaneously. And if you
want zero learning curve, just use asr and other partition:
sudo asr -source /Volumes/"Master Image" -target /Volumes/"Test Image"
Run updates. Test. If fails, roll back. Simple, quick.
Also, any claims that Apple will not "allow" something to be
virtualized are 100% false. Bud Tribble, one of Apple's (and NeXT's)
longtime executives, has said explicitly that Apple is fine with
virtualization as long as everything is properly licensed and *as
long as it is on Apple hardware*. Of course, adding EFI support to
VMware's and Parallels' products is a lot of work, so not it looks
like there is some finger-pointing going on about who's "not
allowing" what.
I know Bud (Actually, I think I might have met you too... WWDC in the
"special side meeting room" I think we were all talking, one of the
conversations were about piping iChat video through SSH)... there was
someone from Wisconsin Edu there... anyhow, as we all know nothing
happens at Apple without Steve's approval, so it would be interesting
to see if someone did come up with an OS X virtualizer and put some
check to make sure it is on OS X hardware (and that is easily done,
I've done it with some of our apps, although it is also easy to hack
for someone with assembly language skills), if Apple would allow it to
continue.
Remember when BootCamp first came out as beta? It was after that
hacker team had hacked Windows to work on a Mac... had they not done
the hack, I think Apple would have held bootcamp until Leopard
release. Apple NEVER betas software as a rule, why was bootcamp
different? If someone came out with a virtualized OS X, Apple might
produce something as well... it's beyond my abilities, but maybe if
someone through a $10,000 reward behind it someone could pull it off.
