Using hardlink forests, Scott's olpc-update does some of that. It's
not integrated to rpm/yum but it could easily be turned into a "cheap
snapshot" without having to wait for ZFS/BTRFS. I am not madly in love
with it, but it does its job.

You'll find - however- that applications and desktop environments
often upgrade their storage formats, so your downgrade path may be
well oiled in the rpm/yum sense, and yet completely unusable for end
users.
