FYI extended attributes being added to squashfs upstream

[Bruno Wolff III]

Lougher recently posted some patches to lkml to add extended attribute
support to squashfs.

I don't know if that will allow live images to not have to use ext3/4
on top of squashfs or not, but thought some people here might be interested
in knowing that eventually squashfs will be able to support some things it
doesn't now.
