Introduction I often find that my tastes for hard drive configurations on my installed systems is a bit outside of the norm. I like playing with thin LVs, BTRFS snapshots, or whatever new thing there is around the corner. The Anaconda UI has been adding support for these fringe cases but I still find it hard to get Anaconda to do what I want in certain cases. An example of this happened most recently when I went to reformat and install Fedora 20 on my laptop.
