Does your application depend on, or report, free disk space? Re: F20 Self Contained Change: OS Installer Support for LVM Thin Provisioning

Once upon a time, Chris Murphy <lists at colorremedies.com> said:
> How does the audit system determine space available? If it's using btrfs configured for raid1 or raid10, df and stat will report the total storage of all devices in the volume, unlike md raid (or even proprietary raid). Instead df reports logs files as using twice as much space.

How is _anything_ (programs, users, admins) supposed to know how much
free space is left on btrfs?  This behavior seems like an admin's
nightmare.
