We want to be able to optionally use UnionFS on the LiveCD (instead of devmapper with Copy-On-Write snapshots) as it's more flexible and faster. As it works on the file system level, removing files added to the writable part of the file system will reduce the size, not add further to it (as it will with devmapper-based copy-on-write snapshots). Also, unionfs allows us to stack more file systems on top of each other, which could be useful from the user's point of view.


Due to the history of instability and the fact that instability in UnionFS will take down the box, we want to make the LiveCD's use of UnionFS optional, and leave the current devmapper + COW solution available as a fall back option.
