No, there isn't any documentation beyond the messages that I've
posted to this list.
As a place to start, here are a few doIts that will illustrate some
of the key concepts in MC2:
MDSlicePanel withAllPackages open
This is the list of all the PackageInfo packages in the image. If you
'Save to File' and enter 'test' as the file name, it will create a
repository in a file called 'test.mcr' and save a snapshot fo the
selected package into it. You can then open that file with the
(MDRepositoryPanel on: (MDFileRepository on: (FileStream
oldFileNamed: 'test.mcr'))) open
This will bring up a repository inspector that will let you load or
merge that snapshot back into the image. Finally, try this:
wc := MDWorkingCopy forImageProxy: MDWorkingCopy defaultImageProxy.
memory := MDMemoryRepository new.
slice := MDPackageInfoSlice named: 'SMBase'.
snapshot _ slice saveFrom: wc to: memory.
This will create a working copy, a repository in memory, and a slice
for the package SMBase. It saves a snapshot of SMBase into the
repository, and then opens explorers so you can look at the contents
of the repository and the snapshot. Hint: all the garbled strings are
instances of MDHashstamp.

I haven't thought about this much, but I think a SAR would work fine.
You could create a SAR that contained an MC2 repository file, your
media and an install script that loaded a snapshot from the repository.
