.Simplified creation of CephFS client keyring
A new command, `ceph fs authorize`, is now supported. The command simplifies creation of `cephx` capabilities for a Ceph File System (CephFS) client user. For example, to grant the `client.1` user read and write access to MDS nodes and read access to Monitor and OSD nodes on a Ceph File System named `cephfs`:
# ceph fs authorize cephfs client.1 rw r
Use this command only when creating new users. It is not possible to modify existing users with `ceph fs authorize`.
