that is the base that i am working from (fuse).
the problem comes when adding support to fuse for xattrs, and the
subsequent use of those xattrs for SE/Linux.
security/selinux/hooks.c cannot cope with the -512 response
"please try later" which the fuse module always always always
sends, in order for fuse to give the userspace daemon a chance
to wake up and smell the roses.
... and i sure ain't gonna hack selinux about!

Truth, honesty and respect are rare commodities that all spring from
the same well: Love. If you love yourself and everyone and everything
around you, funnily and coincidentally enough, life gets a lot better.
