Title:
  nfs-ganesha-rados-grace doesn't work on ARM64

Status in nfs-ganesha package in Ubuntu:
  Fix Released
Status in nfs-ganesha source package in Jammy:
  Fix Committed

Bug description:
  [ Impact ]

  Ganesha's rados backend for HA operation can't be used on aarch64

  [ Test Plan ]

  Install the nfs-ganesha-rados-grace package, run it without arguments.
  It should report a failure to connect to Ceph:

  # ganesha-rados-grace
  rados_conf_read_file: -2
  Can't connect to cluster: -2

  With the current version in Jammy and Kinetic, you instead always get
  the usage directions.

  [ Where problems could occur ]

  Problems could occur around argument parsing on amd64 or arm64 so
  verification should be done that the argument parsing does work.

  [ Other Info ]
   
  Upstream has already landed a fix to this change: https://github.com/nfs-ganesha/nfs-ganesha/commit/3db6bc0cb75fa85ffcebeda1276d195915b84579
