Subject: [PATCH 1/2] xattr.conf: document how libattr itself uses the file
Otherwise users could think that only entries with the `skip` action
are excluded by libattr functions attr_copy_file() and attr_copy_fd()
by default.

Subject: [PATCH 2/2] xattr.conf: remove entries for NFSv4 ACLs namespaces
... in order to make it possible to copy NFSv4 ACLs by GNU coreutils'
implementation of cp(1). There is no way to make GNU coreutils copy
extended attributes that are matched by any entry from /etc/xattr.conf.
GNU coreutils upstream says that NFS-related entries should be removed
from the default /etc/xattr.conf to make copying of NFSv4 ACLs work:
