Title:
  Shutdown hangs on NFS umount: rpc-statd stops too early

Status in nfs-utils package in Ubuntu:
  New

Bug description:
  See description, analysis and solution in
  https://askubuntu.com/questions/1504233/shutdown-hangs-for-one-minute-
  while-umounting-nfs-shares-on-kubuntu-22-04

  Summary: 
  I have two NFS-shares mounted via fstab. On shutdown or reboot, unmounting at least one of them always hangs until the one minute timeout. Before shutdown, they can be unmounted (manually) without any problem.

  Solution is to insert 
  After=rpc-statd.service
  in nfs-client.target. 

  Reportedly, this also affects 24.04
