Hi all,

I'm thinking of different ways to organize my files and xattrs seem a
nice, standardized way to do so (don't ask me exactly what I'm trying to
do, for I only have a slight idea).

The problem is: I can't use them at all. I'm using the default kernel,

and I'm using ext4, evidently.

I've tried doing the following:

$ echo 'asd' > test
$ attr -s user.author -V andre test
attr_set: Operation not supported
Could not set "user.author" for test

but, as you can see, it doesn't work. Running it as root doesn't work,

returning ENOTSUP (operation not supported), so it isn't a problem with

I do have 'attr' from [core] installed so I don't know what else can be
the problem.

Thanks in advance,
