Subject: [PATCH 1/2] xattr.conf: document how libattr itself uses the file
|
|
|
3292e1 |
|
|
|
3292e1 |
Otherwise users could think that only entries with the `skip` action
|
|
|
3292e1 |
are excluded by libattr functions attr_copy_file() and attr_copy_fd()
|
|
|
3292e1 |
by default.

Subject: [PATCH 2/2] xattr.conf: remove entries for NFSv4 ACLs namespaces
|
|
|
3292e1 |
|
|
|
3292e1 |
... in order to make it possible to copy NFSv4 ACLs by GNU coreutils'
|
|
|
3292e1 |
implementation of cp(1). There is no way to make GNU coreutils copy
|
|
|
3292e1 |
extended attributes that are matched by any entry from /etc/xattr.conf.
|
|
|
3292e1 |
|
|
|
3292e1 |
GNU coreutils upstream says that NFS-related entries should be removed
|
|
|
3292e1 |
from the default /etc/xattr.conf to make copying of NFSv4 ACLs work:
