Bug Description

if you set the default subvolume of a btrfs volume like so
mkfs.btrfs /dev/blasterdisk
mount /dev/blasterdisk /mnt
cd /mnt
btrfs subvolume create foo .
btrfs subvolume set-default foo .
cd ..
umount /mnt

and the install WITHOUT reformatting

then the installer will:

1. create subvolumes foo/@ and foo/@home
2. do no error checking: i.e. if a @ subvolume already exists, lets say you set @ as the default, then the system will install into @, and then the installer will crash while trying to mount @home (when it created @/@home)

while your at it you should also fix upstream, and make it work equally bad with btrfs

also, the installer should have a feature to continue where is left off, even if undocumented and hidden

the ideal fix for this is to detect the default subvolume (and perhaps expose it in the interface) and then make the new subvolume childs of that (as it currently does) and then actually properly handle these new subvolumes (broken)
