as I understand it switching from attr1 to attr2 isn't as easy as
just specifying it on the mount point.
you should make your filesystem with attr=2 otherwise the behavior
may not be what you expect.
you can possibly re-add the extended attributes and things will
continue merrily along, but there's some debate apparently over
whether or not adding the attributes to a live file system works as expected.
