Fedora is considering XFS as their default file system. They support three
primary architectures: x86_64, i686, and armv7hl. Do XFS devs have any
reservations about XFS as a default file system on either i686, or arm?
So far the only thing I've run into with kernel 3.13.4-200.fc20.i686+PAE will
not mount an XFS volume larger than 16TB. But I haven't tried filling a < 16TB
volume with a significant amount of data while running 32bit, and anyway it's
just easier to ask if there are other gotchas, or reservations about this
XFS (sdc): file system too large to be mounted on this system.

 The too large warning happens with ext4 at mount time also. A Btrfs volume
mounts OK, although I don't know if it actually withstands significant use.
