Yes, the snapshot will contain the repos, package lists, files, and 
services configuration installed on your system when the snapshot is taken.

After that point, you may restore those repos, packages, files, and 
services on any system of your choosing (Ubuntu 10.04 or 11.10 or 
another system all together such as Fedora or whatnot).

Snap uses the underlying native system tooling to perform operations, 
while representing the snapshots in an abstract manner so that they are 
portable and lightweight.
