Sheepdog won't work at all without 'user_xattr' option.
If you don't use a dedicated device, the space available for sheepdog
will vary when you write/delete data for other reasons.
E.g. you have everything installed in '/' and you use the folder /sheep.
When you add the node to the cluster, sheepdog will assign a wight
based on the free space.
If you write lot's of data in your home folder, free space will change
for sheepdog as well, but the weight of the node doesn't change,
leading to unexpected result (disk full or I/O errors).
It's also much easier to say "use a dedicated device" than explain all
this stuff to a new user.
