Well, what did you expect?  Fusexmp/ is now a mirror of /, which is
customarily owned by root...

See, you are stating '/' --- not Fusexmp/, but '/' which just happens
to get mirrored to Fusexmp/ --- including all the original stat
information like rights and date (you noticed that changed too, didn't
you?).

Sure --- even Fuse can not change the fact that you are not allowed to
write into the root as non-root user...

Does this help?  Shameless plug: would it be a help to rent me (or
some of the others) some more and have this discussion in private?
