The question is: do we strip/add the string namespace when
storing/reading the values in the filesystem.
For native use, I think we do not want to strip, as it is simplier. The
problem arise when mounting a disk from FreeBSD. Here when we ask to
store "user.foo", we mean USER "foo" and not USER "user.foo".
I think we just need a mount option: -o -stripxattr
It would do this mapping:
"system.foo" <-> SYSTEM "foo"
"trusted.foo" <-> SYSTEM "trusted.foo"
"security.foo" <-> SYSTEM "security.foo"
"user.foo" <-> USER "foo"
"anything.foo" <-> USER "anything.foo"
