Version-Release number of selected component (if applicable):
Fedora 24 Alpha-7

How reproducible:


Steps to Reproduce:
1. Install Fedora from Life CD 
2. manual partitioning...
3. select existing partition, mountpoint /

Actual results:
btrfs is not available

Expected results:
--> expected fstype btrfs available

This seems to concern the main installer (and not zyx-liveinstaller), which is anaconda. I'm switching the component setting for the ticket over accordingly.

Comment 2 David Shea 2016-05-02 13:35:35 UTC

A btrfs filesystem can only be created in a btrfs volume, which may span multiple partitions and devices. While it may be possible to reformat a standard partition as btrfs, it is conceptually more complicated than that, and for that reason anaconda requires that the volume be created anew and not from an existing partition.
