Hello,

I found that anaconda is missing support for some handy features of btrfs.

As you may know btrfs support subvolumes so it makes from btrfs something like lvm + filesystem at one (just like zfs). 

This makes user able to populate standart partition like /dev/sda1 and create rest of subvolumes in btrfs (linux lvm can be skipped).

So some checkbox to create subvolumes for standard mountpoints ( /home and /var ) would be really handy. This would be visible only if user selects btrfs based / filesystem.

How to create subvolume

btrfsctl -S home /
btrfsctl -S jack /home # creates subvolume jack under subvolume /home

This will create structure which is really easy to manage/backup in btrfs.
As we're able to create snapshots of filesystem or subvolumes but not directories nor files.

Also making subvolume for user picked up in installation process would be really nice.
