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, which, according to /proc/config.gz has: CONFIG_EXT4_FS_XATTR=y 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, too. I've also made a small C program, but it also fails to set the xattr, returning ENOTSUP (operation not supported), so it isn't a problem with 'attr'. I do have 'attr' from [core] installed so I don't know what else can be the problem. Thanks in advance, Andre
