Hrm. OK, that's not the same as what I thought you meant. Sorry for
the misunderstanding.

I'm not really convinced that this use case is all that common, to be
honest, and I don't see us re-doing our release creation scripts to do
this ("but what about kernels? or lib32?"). But anyways, just to run
the numbers...
The live filesystem is (about) 400MB. All of the 7.0-CURRENT-200706
snapshot is 349M, and out of that, the base distribution is 50MB. So
one could theoretically do this. I think that if you really want such a
thing, it wouldn't be hard to re-master the existing disks to do this.
I'm sure I'm pointing out the obvious when I mention that these problems
would be alleviated (for now) if we assumed DVD-size media when we made
ISOs, rather than standard-length CD-ROM media. The subject has come up
at least once in the past few months, but I can't remember where (if
anywhere) this idea went. I know that at least one CD-ROM vendor makes
combined DVDs, for instance.
I was going to point out that the tools you listed above are available
in the emergency holographic shell environment, but you probably also
wanted disk partitioning tools such as bsdlabel and fdisk, which aren't
there. :-p
Bruce.
