Well, what it means is 'filesystems directly on partitions' rather than
any more complex LVM/btrfs volume-management setup. The filesystem
format it currently uses by default is ext4, but that's not necessarily
written in stone, and in fact the initial plan for F21 was that Server
installs would default to xfs instead. And of course the 'LVM' choice
also uses ext4 - it formats the LVs themselves as ext4 filesystems.

Select a mount point that's part of the volume, click 'Modify...' under
the volume name in the right hand pane, change 'Size policy' to 'Fixed',
enter the new size, click Save, then click Update Settings. You should
see the displayed size of each mount point that's a part of the volume
update to the new value, then you can change the size of the swap
partition.

(now, I'd actually assume that with a size policy of 'As large as
possible' or 'Automatic' for the btrfs volume I could change the size of
the swap partition and the btrfs volume would change size to compensate,
but that doesn't seem to work...)

I don't think I've seen any non-artificial benchmarks that actually bear
this out, btrfs was sort of 'planned' to perform better than ext4 on
SSDs but I'm not at all sure it currently actually does. I run ext4 on
all my SSDs.
