In order to use the openafs-client you have to install the openafs kernel
module (openafs-modules or openafs-modules-dkms).

You may want to edit /etc/openafs/ThisCell to be your current cell.

Afterwards you can enable and start the openafs-client:
  systemctl enable openafs-client.service
  systemctl start openafs-client.service

Please note the following packaging changes:

 * The kaserver / kauth suite is no longer installed. It is obsolete for a
   long time and hopefully not needed anymore. Otherwise please leave a
   comment in the AUR.
   See: http://www.openafs.org/pages/no-more-des.html

 * The server binaries were moved back to /usr/lib/openafs. If you use the
   server you will need to modify your bos config. If you only use the client
   you can safely ignore this.

after making sure that openafs is not running anymore:
